Life data are sometimes modeled with the gamma distribution. Although PROC GENMOD does not analyze censored data or provide other useful lifetime distributions such as the Weibull or lognormal, it can ...

To find an appropriate model for a process distribution, you should consider curves from several distribution families. As shown in this example, you can use the HISTOGRAM statement to fit more than ...

A procedure for interval estimation of the shape parameter of the gamma distribution is proposed which enables the experimenter to obtain upper and lower confidence limits after each observation is ...

The purpose of this expository article is to provide greater access to critical values for testing hypotheses about the shape parameter of a gamma distribution. Among the possible tests, we consider ...
