scipy.stats.rv_discrete.logpmf

rv_discrete.logpmf(k, *args, **kwds)[source]

Log of the probability mass function at k of the given RV.

Parameters :

k : array_like

Quantiles.

arg1, arg2, arg3,... : array_like

The shape parameter(s) for the distribution (see docstring of the instance object for more information).

loc : array_like, optional

Location parameter. Default is 0.

Returns :

logpmf : array_like

Log of the probability mass function evaluated at k.
