`rv_discrete.``isf`(q, *args, **kwds)

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

  Parameters: | q : array_like Upper tail probability. 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=0).
  Returns: | k : ndarray or scalar Quantile corresponding to the upper tail probability, q.
