摘要:Let π= π1- π2 be the difference of two independent proportions related to two populations. We study the test H0: π ≥0 against different alternatives, in the Bayesian context. The various Bayesian approaches use standard beta distribution...

摘要:For thecase where the multivariate normal population does not have null correlations,we give the exact expression of the distribution of the sample matrix ofcorrelations R , with the samplevariances acting as parameters. Also, the distribution of its determinant isestablished in ...

摘要:The ratio R of two random quantities is frequently encountered in probability and statistics. But while for unidimensional statistical variables the distribution of R can be computed relatively easily, for symmetric positive definite random matrices, this ratio can take various f...
