The formula of Mean: In statistics, "mean" is a measure of central tendency, calculated by summing up all the values in a dataset and dividing by the number of data points. The single numerical value ...

In this paper we consider large θ approximations for the stationary distribution of the neutral infinite alleles model as described by the the Poisson-Dirichlet distribution with parameter θ. We prove ...

Formulas to determine the necessary sample sizes for parametric tests of group comparisons are available from several sources and appropriate when population distributions are normal. However, in the ...
