Some Aspects of Statistical Inference and Its Relation to Life Testing Models is about Statistical Inference in the context of wide ranging applications in the present day scenario. In life testing and reliability problems, both Classical & Bayesian inferences have widely been used. The data for which the statistical methods are applied to estimate the parameters and reliability are obtained from life tests. In a life test, a number of items are subjected to the test and the data are recorded. Naturally, the failure times will be order statistics. The theory of order statistics plays an important role in the analysis of life test data. As a study of some of the key aspects of statistical inference in the context of life testing models, it will help young researchers to explore the area further.
