摘要

In the problem of estimating the parameter of the underlying probability distribution, a su¢cient statistic should be one that summarizes and exhausts in itself all the relevant information on the parameter that is contained in the sample. A similar basic problem of statistics is that of predicting a future (that is, not yet observed) random variable on the basis of some existing observable random variables when the parameter of the underlying probability distribution does not concern us directly. Likewise, we are looking for a statistic as one that is exhaustive of all the relevant information on the future random variable that is available in the current observable random variables. The notion of adequate statistics initiated by Fisher [4] and Skibinsky [8] would deal with this concern. Subsequently, it has been extensively investigated in literatures such as [1,2,6,9-11]. In this article, we make a comprehensive study of …nding an adequate statistic for the total time on test when the data is assumed to be exponentially distributed and censored after the r-th failure.
