An interpretation is given of ABOUAMMOH'S (1987) discrete analogue of the (one-dimensional) definition of a-unimodality by Olshen and Savage. The concepts are of some interest in the context of selfdecomposability. 相似文献

We use the independence of the integer and fractional parts of exponentially distributed random variables to obtain expressions for the order statistics from a geometric distribution. As our main result we show that a strong form of this independence characterizes the exponential distribution. 相似文献

Abstract A new and very simple test for uniformity is proposed. An exact formula for the distribution under H0 of the corresponding test statistic is derived. This formula is only suitable for computer-oriented use. For other circumstances a table of critical values is given. The power of the test is compared with that of two well-known alternatives: the χ2 -test and the Kolmogorov-Smirnov test. 相似文献
