function

`scipy.stats._multivariate:dirichlet_multinomial_gen.var`

source: /scipy/stats/_multivariate.py :6945

Signature

def var ( self , alpha , n )

Summary

The variance of the Dirichlet multinomial distribution.

Parameters

alpha : array_like: The concentration parameters. The number of entries along the last axis determines the dimensionality of the distribution. Each entry must be strictly positive.
n : int or array_like: The number of trials. Each element must be a non-negative integer.

Returns

: out: array_like: The variances of the components of the distribution. This is the diagonal of the covariance matrix of the distribution.
