v0.25.2

0.25.2 - 2020-08-08

New features

• Spline CoxPHFitter can now use strata.

API Changes

• a small parameterization change of the spline CoxPHFitter. The linear term in the spline part was moved to a new Intercept term in the beta_.
• n_baseline_knots in the spline CoxPHFitter now refers to all knots, and not just interior knots (this was confusing to me, the author.). So add 2 to n_baseline_knots to recover the identical model as previously.

Bug fixes

• fix splines CoxPHFitter with when predict_hazard was called.
• fix some exception imports I missed.
• fix log-likelihood p-value in splines CoxPHFitter
