'Returns a scipy distribution object corresponding to the
distribution of uncensored endog (duration) values for each
case.
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 wihtin a stratum.'
