A truncated type I generalized logistic distribution could be particularly useful as a lifetime model by requiring a positive domain . In this thesis, the truncated type I generalized logistic distribution is described and some of its properties investigated. Some limiting and transformed distributions of this distribution are presented. One of the objectives of this study is the estimation of the parameters, reliability and hazard rate functions, using the maximum likelihood method. Newton- Raphson iteration scheme is used to solve the likelihood equations. The uniformly minimum variance unbiased estimate of a function of the shape parameter is obtained assuming that the other parameters are known. Bayesian prediction bounds for some order statistics of future observations from the truncated type I generalized logistic distribution are obtained. The prior information about the true value of the shape parameter is measured by informative and non-informative- priors assuming that the other parameters are known. Numerical examples are used to illustrate the procedure  Supervisor : Dr. Issam Khalaf Al-Husseini  Thesis Type : Master Thesis  Publishing Year : 1418 AH 1997 AD  Co-Supervisor : Prof. Gannat Ramadan Al-Dayian  Added Date : Saturday, June 14, 2008  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email أريج محمد العنقري Alanqari, Areej M Researcher Master   Files File Name Type Description  23545.pdf pdf    23546.pdf pdf   Back To Researches Page
