Stochastic Processes Model And Its Application In Operations Research, Chun Yuan Hsu
Stochastic Processes Model And Its Application In Operations Research, Chun Yuan Hsu
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Just as the probability theory is regarded as the study of mathematical models of random phenomena, the theory of stochastic processes plays an important role in the investigation of random phenomena depending on time. A random phenomenon that arises through a process which is developing in time and controlled by some probability law is called a stochastic process. Thus, stochastic processes can be referred to as the dynamic part of the probability theory. We will now give a formal definition of a stochastic process.
Let T be a set which is called the index set (thought of as time), then, …
Computer Programs For Incomplete Block Designs, Fred Miller
Computer Programs For Incomplete Block Designs, Fred Miller
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
In most disciplines where research is involved, there exists an occasional problem of having minimal facilities and/or funds for conducting experiments. This often necessitates the use of designs known as incomplete block designs.
Since the calculations needed to provide an appropriate statistical analysis are somewhat tedious, particularJ..y in the larger designs, it is advantageous to have computer programs to do the necessary calculations.
There are several computer programs at Utah State University written in Fortran II language with Forcom subroutines that perform the analyses for incomplete block designs. These programs, for the most part, were authored by Justus Seely and …

In the last several years monte-carlo simulation has become a major tool for the analysis of complex queuing systems which are no readily amenable to analysis by conventional mathematical methods. By a complex queueing system is mean a system composed of, physically or by analogy, a network of stations or servers with traffic units moving through all or some of the servers, into the system and out or around within the system. A traffic unit desiring service by a server may either have to enter a queue first or may be served immediately. Such systems have been simulated often with …
A Study Of The Exponential Distirbutions And Their Applications, Michael Chang-Yu Wang
A Study Of The Exponential Distirbutions And Their Applications, Michael Chang-Yu Wang
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The exponential distribution is a widely known distribution i n statistical theory. It can be regarded as the continuous analogue of the Poisson distribution, discussed by S. D. Poisson in 1837. The Poisson is a limiting form of the Binomial distribution which can be t race d back as early as 1700, discussed by James Bernoulli. A paper by Marsden and Barratt (1911) on the radioactive disintegration of thorium gives a typical frequency distribution which follows the exponential law (8, p. 89). The exponential distribution has achieved importance recently in connection with the theory of stochastic process and has found …
Partially Balanced Incomplete Block Designs, Yaw-Tarng Shih
Partially Balanced Incomplete Block Designs, Yaw-Tarng Shih
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
In balanced incomplete block designs, each pair of treatments is compared with equal precision, and each treatment is paired with every other treatment an equal number of times with in a common block; A is a constant for all treatments. There is one associate class for each treatment in balanced incomplete block designs. These are the most important balanced incomplete block designs, but the need sometimes arises for others; either because no suitable balanced incomplete block design exists, or because, for example, it is necessary to make some comparisons more precisely than others. We can see balanced incomplete block designs …
Generation Of Random Numbers, Keith H. Eberhard
Generation Of Random Numbers, Keith H. Eberhard
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Subroutines are written to generate random numbers on the computer. Depending on the subroutine used, the generated random numbers follow the uniform, binomial, normal, chi-square, t, F, or gamma distribution. Each subroutine is tested using the chi-square goodness of fit test to verify that the random numbers generated by each subroutine follow the statistical distribution for which it is written. The interpretation of the test results indicates that each subroutine generates random numbers which closely approximates the theoretical distribution for which it is designed.
The approach used in the subroutine which generates gamma distributed random numbers involves the use of …
Analysis Of Contingency Tables, James Joseph Biundo
Analysis Of Contingency Tables, James Joseph Biundo
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Two methods of analyzing multi-dimensional frequency data are detailed.
The Second Order Exponential (SOE) model is applicable for dichotomous classifications. The distribution has two sets of parameters, ϴi's and ϴj's. The ϴi's are interpreted as the log of the odds of the marginal probabilities if no two factor relationships exist. Or if all ϴij are not zero, then the ϴi's are analogous to a main effect in a 2m factorial analysis, (m = number of factors or classifications). The ϴif's may be interpreted as a measure and direction …

Simulating Regional Interindustry Models For Western States, William A. Schaffer, Kong Chu
Simulating Regional Interindustry Models For Western States, William A. Schaffer, Kong Chu
Applications
Although regional input-output models are now most frequently constructed on the basis of reasonably adequate surveys, simulation (estimating) techniques not based on original survey data are still in use by many regional scientists for quick and less costly results. We will modify our original aggregation procedures, examine our results through several statistical tests of tables constructed for three Western states, and discuss a possible correction procedure for improving raw estimates of interindustry transactions.

An Instructional Method For Self-Administered Medications, Beryl Marx, Lorene Russell
Loma Linda University Electronic Theses, Dissertations & Projects
An experimental study was done to determine the effectiveness of an instructional method for older ambulatory patients taking prescribed self-administered medications. This method was developed to emphasize the physicians' specific orders, the purpose of medications, feedback of instruction and a plan for remembering and recording medications. The hypothesis tested was that a selected group of ambulatory patients age 60 and over with the instructional method would make significantly fewer errors than a similar control group with no instructions.
Sixty private patients from the Loma Linda University Hospital outpatient department were selected and randomly placed in the experimental and control groups. …

Masseter Muscle Position Relative To Skeletal Open Bite And Skeletal Closed Bite, Alonzo David Proctor
Loma Linda University Electronic Theses, Dissertations & Projects
Modification of cephalometric roentgenographic procedures provided a means to identify the anterior borders of the right and left masseter muscles and relate them to surrounding dentoskeletal elements. Attachment of short, stiff, wires to the cheeks in a position superficial to the anterior borders of the muscles, subsequent to palpation and prior to exposure of the roentgenographic film, was the procedure used. The bi-lateral images projected on the film were averaged and traced along with dentoskeletal elements including those associated with skeletal type. This line representing the anterior border of the musculature was used to assess muscle position in the vertical …

Computer Analysis Of Consumer Attitude And Consumption Data For Fluid Milk Products, James Reed Fisher
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The American public, with a per capita disposable income currently at an all time high, has become a source of vital concern to dairy market researchers. The unique socio-economic structure of the present generation causes the dairy industry to be concerned with how the consumer view its products. Effective education and advertising programs must be developed to attract the taste and meet the demands of the consumer.
Two factors which greatly influence market research and advertising programs are the attitude of the consumer toward a given product and the relationship of attitude to the degree of actual milk consumption. To …

The Relationship Of Church Activity Of Parents Of Lds Seminary Students To The Attendance Of Seminary Students At Church, Ronald D. Firth
The Relationship Of Church Activity Of Parents Of Lds Seminary Students To The Attendance Of Seminary Students At Church, Ronald D. Firth
Theses and Dissertations
It has been observed that not all L.D.S. Seminary students are active in church attendance. There is little doubt in the minds of educators that parents affect a great deal the activities of their children.
The purpose of the study was to learn what relationship, if any, existed between a seminary student's church attendance and the church activities of his parents, and to find out which, if any, of five specific areas of parental church activity had the most positive effect on a student's church attendance.
Based on his experience in the church, the writer chose the following areas of …
