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

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

Parameters:

• q (array_like) – upper tail probability
• arg2, arg3,.. (arg1,) – The shape parameter(s) for the distribution (see docstring of the instance object for more information)
• loc (array_like, optional) – location parameter (default=0)
• scale (array_like, optional) – scale parameter (default=1)

Returns:

x – Quantile corresponding to the upper tail probability q.

Return type:

ndarray or scalar
