A New Confidence Interval For The Mean Of A Normal Distribution, David Lee Wallace Jun 1971

A New Confidence Interval For The Mean Of A Normal Distribution, David Lee Wallace

All Master's Theses

A typical problem in statistical inference is the following: An experimenter is confronted with a density function f(x; ϴ) which describes the underlying population of measurements. The form of f may or may not be known, and ϴ is a parameter (possibly vector-valued) which describes the population. The statistician's job is to estimate or to test hypotheses about the unknown parameter ϴ. In this paper, we shall consider interval estimation of the mean of the normal density function.

Optimum Estimators And Strategies In Survey Sampling., M. K. Ramakrishnan Dr. Feb 1971

Optimum Estimators And Strategies In Survey Sampling., M. K. Ramakrishnan Dr.

Doctoral Theses

This thesis consists of nine chapters. In the first chapter we give the basic concepts and definitions and also a broad review of the literature related to the problems considered in this thesis. The second and third chapters are devoted to a detailed modified comparison of sampling with and without replacement, for the case of equal and unequal probability sampling respectively. In the fourth and fifth chapters we discuss the criteria of hyper-admissibility and linear suf2iciency for the choice of an optimum estimator for a given sampling design. The succeeding three chapters have as their main objective the central problem …

Some Stochastic Models In Reliability., R. Natarajan Dr. Feb 1969

Some Stochastic Models In Reliability., R. Natarajan Dr.

Doctoral Theses

The work presented in this thesis was carried out under the supervision of Dr. J. Sethuraman, Research & Training School, Indian Statistical Institute, Calcutta, and is devoted to the study of some stochastic models of standby and parallel redundant systems. Some of the reliability characteristics studied are the expected time to system failure, the long-run availability, expected number of system failures in a given interval of time, interval reliability etc. These reliability characteristics will be useful in the better design of systems and making management decisions in improving system reliability.The investigations carried out in this thesis are presented in four …

Some Statistical Studies On Languages., Nikhilesh Bhattacharya Dr.

Doctoral Theses

The investigations reported in the present the is were started towards the end of 1957 and carried along internittently amidst teaching and professnional work on ample surveys and econometrics, Curiosity provided the major inpulse. The authors ambition was, initially, to throw up sone numerical tubles for Benguli, Sanskrit, Prakrit and Pali, such usüre found for many western languages in Herdans (1956) Language as Choice and Chance. Grudually, as the work progressed, the view changed and more analytical studies suggested themselves. Some of the se latter have been completed in arrovidional manner and re ported in the present thesis.Chapter 1 attempts …

Simulation Of Mathematical Models In Genetic Analysis, Dinesh Govindal Patel May 1964

Simulation Of Mathematical Models In Genetic Analysis, Dinesh Govindal Patel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In recent years a new field of statistics has become of importance in many branches of experimental science. This is the Monte Carlo Method, so called because it is based on simulation of stochastic processes. By stochastic process, it is meant some possible physical process in the real world that has some random or stochastic element in its structure. This is the subject which may appropriately be called the dynamic part of statistics or the statistics of "change," in contrast with the static statistical problems which have so far been the more systematically studied. Many obvious examples of such processes …

Convolution Properties Of Distributions On Topological Groups., S. R. S. Varadhan Dr. Mar 1963

Convolution Properties Of Distributions On Topological Groups., S. R. S. Varadhan Dr.

Doctoral Theses

The collection of probability distributions on the real line which is a semigroup under the convolution operation and topological space under weak convergence has attracted, during the last quarter of a century, the attention of such great mathematicians as Khintchine, Kolmogorov, Bawly, Levy and others. Their results constitute a deep analysis of the factorization problems on the one hand and the asymptotic behavior of infinite convolutions on the other. However, a complete and systematic investigation of these problems is not available in considerable generality. The aim of the present thesis is to investigate the topological and algebraic properties and the …
