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
