Semi Parametric Estimation Of Some Reliability Measures Of Geometric Distribution, Mathachan Pathiyil, E.S. Jeevanand

Journal of Modern Applied Statistical Methods

Semi parametric estimators of the survival function, the hazard function, and the mean residual life function of geometric distribution using uncensored and Type II censored samples are obtained. The accuracy of the estimators so obtained is investigated empirically using simulated samples. The results are applied to a real life data set for illustration.

Large Deviations Techniques For Error Exponents To Multiple Hypothesis Lao Testing, Leader Navaei

Journal of Modern Applied Statistical Methods

In this article the problem of multiple hypotheses testing using a theory of large deviations is studied. The reliability matrix of Logarithmically Asymptotically Optimal (LAO) tests is introduced and described, and the conditions for the positive of all its elements are indicated.

Interference On Overlapping Coefficients In Two Exponential Populations, Mohammad Fraiwan Al-Saleh, Hani M. Samawi

Journal of Modern Applied Statistical Methods

Three measures of overlap, namely Matusita’s measureρ , Morisita’s measure λ and Weitzman’s measure Δ are investigated in this article for two exponential populations with different means. It is well that the estimators of those measures of overlap are biased. The bias is of these estimators depends on the unknown overlap parameters. There are no closed-form, exact formulas, for those estimators variances or their exact sampling distributions. Monte Carlo evaluations are used to study the bias and precision of the proposed overlap measures. Bootstrap method and Taylor series approximation are used to construct confidence intervals for the overlap measures

Performance Of Some Correlation Coefficients When Applied To Zero-Clustered Data, L. W. Huson

Journal of Modern Applied Statistical Methods

Zero-clustered data occur widely in medical research and are characterised by the presence of a group of observations of value zero in a distribution of otherwise continuous non-negative responses. A simulation study was conducted to investigate the properties of a number of correlation coefficients applied to samples of zero-clustered data.

The Correlation Coefficients, Rudy A. Gideon

Journal of Modern Applied Statistical Methods

A generalized method of defining and interpreting correlation coefficients is given. Seven correlation coefficients are defined — three for continuous data and four on the ranks of the data. A quick calculation of the rank based correlation coefficients using a 0-1 graph-matrix is shown. Examples and comparisons are given.

Covariate Dependent Markov Models For Analysis Of Repeated Binary Outcomes, M.A. Islam, R.I. Chowdhury, K.P. Singh

Journal of Modern Applied Statistical Methods

The covariate dependence in a higher order Markov models is examined. First order Markov models with covariate dependence are discussed and are generalized for higher order. A simple alternative is also proposed. The estimation procedure is discussed for higher order with a number of covariates. The proposed model takes into account the past transitions. Transitions are fitted and are tested in order to examine their influence on the most recent transitions. Applications are illustrated using maternal morbidity during pregnancy. The binary outcome at each visit during pregnancy is observed for each subject and then the covariate dependent Markov models are …

Operating Characteristics Of The Dif Mimic Approach Using Jöreskog’S Covariance Matrix With Ml And Wls Estimation For Short Scales, Michaela N. Gelin, Bruno D. Zumbo

Journal of Modern Applied Statistical Methods

Type I error rate of a structural equation modeling (SEM) approach for investigating differential item functioning (DIF) in short scales was studied. Muthén’s SEM model for DIF was examined using a covariance matrix (Jöreskog, 2002). It is conditioned on the latent variable, while testing the effect of the grouping variable over-and-above the underlying latent variable. Thus, it is a multiple-indicators, multiple-causes (MIMIC) DIF model. Type I error rates were determined using data reflective of short scales with ordinal item response formats typically found in the social and behavioral sciences. Results indicate Type I error rates for the DIF MIMIC model, …

A Simple Method For Finding Emperical Liklihood Type Intervals For The Roc Curve, Ayman Baklizi

Journal of Modern Applied Statistical Methods

Interval estimation of the ROC curve is considered using the empirical likelihood techniques. Suggested is a procedure that is very simple computationally and avoids the constrained optimization problems usually faced with empirical likelihood methods. Various modifications are suggested and the performance of the intervals is evaluated in terms of their coverage probability. The results show that some of the suggested intervals compete well with other intervals known in the literature.

The Effect Of Garch (1,1) On The Granger Causality Test In Stable Var Models, Panagiotis Mantalos, Ghazi Shukur, Pär Sjölander

Journal of Modern Applied Statistical Methods

Using Monte Carlo methods, the properties of Granger causality test in stable VAR models are studied under the presence of different magnitudes of GARCH effects in the error terms. Analysis reveals that substantial GARCH effects influence the size properties of the Granger causality test, especially in small samples. The power functions of the test are usually slightly lower when GARCH effects are imposed among the residuals compared with the case of white noise residuals.

Generalized Linear Mixed-Effects Models For The Analysis Of Odor Detection Data, Sandra Hall, Matthew S. Mayo, Xu-Feng Niu, James C. Walker

Journal of Modern Applied Statistical Methods

Olfactory detection has become a science of interest. Seven individuals’ odor detection abilities are explored and an attempt is made to characterize all subjects with one generalized linear mixed effects model. Two methods of fitting the models were used and simulations were conducted to discover which method yielded the best results.

A Modified X̄ Control Chart For Samples Drawn From Finite Populations, Michael B. C. Khoo

Journal of Modern Applied Statistical Methods

The X̄ chart works well under the assumption of random sampling from infinite populations. However, many process monitoring scenarios may consist of random sampling from finite populations. A modified X̄ chart is proposed in this article to solve the problems encountered by the standard X̄ chart when samples are drawn from finite populations.

Optimum Choice Of Covariates For A Series Of Sbibds Obtained Through Projective Geometry, Ganesh Dutta, Premadhis Das, Nripes Kumar Mandal

Journal of Modern Applied Statistical Methods

A block design set up is considered in presence of a number of controllable covariates. The problem is that of choosing the values of the covariates so that for a given block design, it is optimum in the sense of attaining minimum variance for the estimation of each of the covariate parameters. In case of incomplete block designs, the choice of the values of the covariates depends heavily on the allocation of treatments to the plots of blocks; more specifically on the method of construction of the incomplete block design. In this paper the situation where the block design is …

A New Generalization Of Negative Ploya-Eggenberger Distribution And Its Applications, Anwar Hassan, Sheikh Nilal Ahmad

Journal of Modern Applied Statistical Methods

A new generalization of negative Polya-Eggenberger distribution (GNPED) has been obtained by mixing the negative binomial distribution with generalized beta distribution-Π defined by Nadarajah and Kotz (2003). Some special cases and properties of GNPED have been studied. Further, the proposed model has been fitted to two data sets (used by Gupta & Ong, 2004) that provide a satisfactory fit and better alternative as compared to negative binomial and some of its mixture models and extensions. Also, the negative Polya-Eggenberger distribution (NPED), obtained by mixing negative binomial with beta distribution of I-kind, has been fitted to the same data sets for …

The Dangers Of Automobile Travel: A Reconsideration, Roger Roots

Roger Roots

America's reliance on automobile transportation has attracted the scorn of academics for decades. Automobiles, it is said, are dangerous to life and limb, environmentally unfriendly, and wasteful of space and resources. Moreover, say the critics, automobiles produce inefficient individualistic social behavior that balkanizes com munities and shatters the otherwise cohesive nature of American life. This article examines the costs and benefits of U.S. automobile travel from a historic perspective. First, it compares the safety of automobile travel with the horse and steam-powered travel that preceded it. It then briefly addresses the changes wrought by American automobiles in terms of their …

Accommodative Strategies In Nigerian Federalism Since Independence, Ozy B. Orluwene Jp

Dr Ozy B.Orluwene,JP

Abstract This paper primarily illustrates how the practice of federalism in Nigeria has made her an epitome and pioneer of federalism in Africa in the use of power sharing mechanism and practice to promote inter- ethnic inclusiveness or discourage sectional imbalance and bias in decision making processes. This practice of federalism in Nigeria has also validated the idea that federalism is adopted with a view to ensuring unity of the people and faith in their father-land so as to further the end of liberty, equality and justice in the country. This observation has led us to conclude that it is …

Corruption, Governance And Political Instability In Nigeria, Omololu Toluwanimi Omololu

Omololu Michael FAGBADEBO

The Nigerian State is a victim of high-level corruption, bad governance, political instability and a cyclical legitimacy crisis. Consequently, national development is retarded, and the political environment uncertain. The country’s authoritarian leadership faced a legitimacy crisis, political intrigues, in an ethnically - differentiated polity, where ethnic competition for resources drove much of the pervasive corruption and profligacy. While the political gladiators constantly manipulated the people and the political processes to advance their own selfish agenda, the society remained pauperized, and the people wallowed in abject poverty. This invariably led to weak legitimacy, as the citizens lacked faith in their political …

Construir, Destruir Y Escribir La Ciudad: Iglesia, Industria Y Guerra En Querétaro (1839-1881), Alexander Montoya Prada

Alexander Montoya Prada

A mediados del siglo XIX en la ciudad mexicana de Querétaro, las fábricas de Cayetano Rubio, el proceso de desamortización de bienes de la Iglesia y el sitio militar de 1867 contra las tropas del emperador Maximiliano, cambiaron su paisaje urbano y la forma en que lo vivían e interpretaban los lugareños y visitantes. La industria, la iglesia y la guerra, se constituían en tres dimensiones fundamentales de la historia y la vida de la ciudad, que son tratadas en la “Guía del viajero en Querétaro. Apuntes históricos, geográficos y estadísticos de la ciudad”, escrita por Celestino Díaz. Sobre este …

R&D Policy In The United States: The Promotion Of Nanotechnology, Philip Shapira, Jue Wang

Philip Shapira

This case study reviews the evolution of nanotechnology policies and programmes in the United States with a particular focus on three thematic areas: governance, interactions among R&D policies, and interaction between R&D policy and non-R&D policies. Federal R&D policy in nanotechnology has moved through several stages, including initial exploration before the 1980s, the promotion of scientific and technological breakthroughs in the 1980s, policy development in the 1990s and multiagency national initiatives in the 2000s. Since 2001, the major federal R&D policy mechanism in nanotechnology in the US has been the National Nanotechnology Initiative (NNI). NNI promotes policy deliberation and, most …

Fringe Candidates Can Change Perceptions Of Centrist Candidates, Renan Levine

Renan Levine

Two experiments demonstrate that adding an extreme third candidate to the choice set causes perceptions of the nearest candidate to appear more centrist. This change in perceptions is large enough to cause this candidate to appear closer to many voters. causal mechanism driving the shift in perceptions is attributed to information about the range of possible values provided by the extreme candidate. This is consistent with “range effects” identified by Parducci (1965) and used to explain behavior in a wide variety of other contexts. In politics, range effects may help a major party candidate win the median voter when an …

La Tragedia De Los Comunes En La Competencia Vertical Entre Jurisdicciones, Martin Enrique Krause

Martin Krause

Los beneficios de la competencia institucional se alcanzan bajo ciertas normas que impiden la violación de derechos y la depredación de los recursos. La competencia horizontal puede tomar la forma de agresión violenta entre jurisdicciones (guerra) o la de cooperación y comercio. Su impacto puede ser “negativo” si substrae recursos de gobiernos benevolentes comprometidos con el bienestar general de la comunidad, pero “positivos” si se los considera como otra forma de controlar el Leviatán. La competencia vertical muestra los mismos controles “positivos” potenciales y la misma necesidad de ciertas reglas para cumplir ese papel. Son similares a la definición estricta …

El Desafío Político De Gobernar La Ciudad, Fernando Carrión Mena

Fernando Carrión Mena

Las ciudades latinoamericanas están cambiando. De la «ciudad frontera», con una lógica de urbanización basada en la expansión de las periferias y la metropolización industrial, se ha pasado a una «ciudad en red», resultado de la globalización, la reforma del Estado y los cambios demográficos. En este nuevo contexto, se perciben en la región dos modelos políticos de gobierno de la ciudad: el de la ciudad empresarial privada, que recurre al mercado para inyectarle eficiencia a la gestión urbana, y el de la ciudad inclusiva, basada en una revalorización del espacio público y la promoción de derechos. La exitosa experiencia …

Widespread Economic Doubts, Julio J. Prado

Julio J Prado

Many people think –perhaps with just reason- that the economy is a boring theoretical science, and that it does not have its feet upon the ground. In order to try to change that perception, we are going to propound for ourselves some day to day questions, to which we can provide an answer (to the extent possible) with a bit of economic “logic”.

Dudas Económicas Existenciales, Julio J. Prado

Julio J Prado

Muchas personas creen -con justa razón quizás- que la economía es una ciencia aburrida, teórica y que no tiene los pies en la tierra. Para tratar de cambiar esa percepción, vamos a plantearnos algunas preguntas del día a día, a las que daremos respuesta (en la medida de lo posible) con algo de “lógica” económica.

Perceptions Of Value And Value Beyond Perceptions: Measuring The Quality And Value Of Journal Article Readings, Carol Tenopir, Donald W. King

Carol Tenopir

When measuring quality and value of journals, what is being measured, to whom does the value accrue, and why the measurement is being done must be considered. Both implicit and explicit measures of quality and value are possible. Preliminary results of ongoing readership research show that academic library e-journal collections have both purchase and use value to academic faculty. They spend their time reading, read many articles each year, and reading benefits their work in many ways.

Cultural Discourse Analysis: Communication Practices And Intercultural Encounters, Donal Carbaugh

Donal Carbaugh

The field of intercultural communication has been criticized for failing to produce studies which focus on actual practices of communication, especially of intercultural encounters. Of particular interest have been cultural analyses of social interactions, as well as analyses of the intercultural dynamics that are involved in those interactions. This article addresses these concerns by presenting a framework for the cultural analysis of discourse that has been presented and used in previous literature(e.g., Carbaugh, 1988a, 1990, 2005; Carbaugh, Gibson, and Milburn, 1997). Indebted to the ethnography of communication (Hymes, 1972), and interpretive anthropology (Geertz, 1973), this particular analytic procedure is one …

Klipsun Magazine, 2007, Volume 38, Issue 02 - November, Brittney Leirdahl

Klipsun Magazine

Past. Present. Future.

This phrase has a different meaning to everyone. My history dates back 22 years. Klipsun is more than 50 years old. And a few stories in this magazine are about artifacts dating back hundreds of years.

No matter what this phrase means to you, we all have history. Some of us want to never look back and just continue forward to see what our future entails. I personally am terrified of my future and seem to rely heavily on my past. An unfamiliar future scares me, while a past of familiarity comforts me.

For many, reading historical …
