statsmodels.distributions.discrete.DiscretizedCount.isf

DiscretizedCount.isf(q, *args, **kwds)

Inverse survival function (inverse of sf) at q of the given RV.

Parameters:

• q (array_like) – Upper tail probability.

• arg1 (array_like) – The shape parameter(s) for the distribution (see docstring of the instance object for more information).

• arg2 (array_like) – The shape parameter(s) for the distribution (see docstring of the instance object for more information).

• arg3 (array_like) – The shape parameter(s) for the distribution (see docstring of the instance object for more information).

• ... (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=0).

Returns:

k – Quantile corresponding to the upper tail probability, q.

Return type:

ndarray or scalar
