The first one tests hypotheses on the shape parameter of a single gamma distribution. We numerically examine the performance of this test and find that it controls Type I error rate for small samples. To compare shape parameters of a set of independent gamma populations, we develop a test ...

The exact density of the statistic ln \\\(\\\bar x/ilde x\\\) , where \\\(\\\bar x\\\) and \\\(ilde x\\\) denote, respectively, the arithmetic and the geometric means of a random sample from a two-parameter gamma distribution, is obtained in a computable form using the te...

A procedure is proposed in this paper for testing the shape parameter, β of the Weibull distribution. The test statistic which is based on the extremal quotient, possesses a monotone property which makes it possible for rejection earlier than the last planned observation of the null hypothesis,H...
In this paper a derivation of the minimum variance unbiased (MVU) point estimate for the scale parameter of a shifted (left-truncated) Gamma distribution will be given when the shape parameter, ±, is a known integer. The explicit expression derived in this paper is of independent interest, ...
