In this paper the robustness of some of the existing tests for the exponential distribution when some outliers are present is reviewed. It is noted that the tests proposed by Epstein and Sobel [4] can ...

In some life testing situations the minimum life can be nonzero. This paper develops O. C. curves for a hypothesis test concerning the minimum life where the underlying failure distribution is ...

Figure 1: Frequency distributions of absolute fitness in selective (a) and permissive (b) environments. Figure 2: Distribution of fitness effects among 18 beneficial mutants assayed in the permissive ...
