# scipy.stats.rv_discrete.logsf

`rv_discrete.``logsf`(k, *args, **kwds)

  Log of the survival function of the given RV.

  Returns the log of the “survival function,” defined as 1 - `cdf`, evaluated at k.

  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=0).
  Returns: | logsf : ndarray Log of the survival function evaluated at k.
