The joint density function of the sample mean and sample variance is recursively derived for samples from a population with density function f where f (x) > 0 cilinost syervi,vheie, everywhere continuous and has certain integral properties. For populations where f does not have these integral properties, this joint density is an approximation. This joint density-function is used to derive the density function of the t-statistic for samples from f. The family of generalized normal density functions is used for an example. The approximation for the t-density is given for that family. For some specific members of the family, the true a probabilities for the approximations are tabled and compared to the results of a simulation study. |
