statsmodels.duration.hazard_regression.PHReg.get_distribution

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.
