Abstract: | Summary This paper analyses the shift in parameter of a life test model. This analysis depends on the prediction of order statistics
in future samples based on order statistics in a series of earlier samples in life tests having a general exponential model.
While a series ofk samples are being drawn, model itself undergoes a change. Firstly, a single shift is considered and the effect of this shift
on the variance is discussed. Generalisation withs shifts (s≦k) ink samples in also taken up and the semi-or-used priors (SOUPS) have been used to get predictive distributions. Finally, shift
afteri (i≦k) stages, from exponential to gamma model is considered and for this case effect of the shift on the variance as well as on
the Bayesian prediction region (BPR) is analysed along with set of tables. |
