ANALYSIS OF ACCELERATED LIFE TESTING USING GEOMETRIC PROCESS FOR FRECHET DISTRIBUTION

Sana Shahab, Ariful Islam

In Accelerated life testing (ALT), a log-linear relationship between life and stress is used. However instead of original parameters, transformed parameters are used for estimation which loose originality due to various assumptions. In this paper the geometric process is used for the analysis of ALT under constant stress for the Frechet Distribution. The maximum likelihood procedure is followed to estimate the parameters of the model and also evaluate the performance of confidence intervals through simulation
