(params)[source]¶ Returns a scipy distribution object corresponding to the distribution of uncensored endog (duration) values for each case.
- Parameters
params : array_like

The distributions are obtained from a simple discrete estimate of the survivor function that puts all mass on the observed failure times within a stratum.
