PHReg.baseline_cumulative_hazard(params) [source]

Estimate the baseline cumulative hazard and survival functions.

Parameters:

Parameters:	params : ndarray The model parameters.
Returns:	A list of triples (time, hazard, survival) containing the time values and corresponding cumulative hazard and survival function values for each stratum.

params : ndarray

The model parameters.

Returns:

A list of triples (time, hazard, survival) containing the time

values and corresponding cumulative hazard and survival

function values for each stratum.
