`scipy.stats._multivariate:dirichlet_multinomial_gen.cov`

source: /scipy/stats/_multivariate.py :6963

Signature

def cov ( self , alpha , n )

Summary

Covariance matrix of a 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 covariance matrix of the distribution.
