PHReg.
get_distribution
(params)[source]¶ Returns a scipy distribution object corresponding to the distribution of uncensored endog (duration) values for each case.
Parameters: params : array-like
The proportional hazards model parameters.
Returns: A list of objects of type scipy.stats.distributions.rv_discrete
Notes
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.
