0.21.2

New features
  • New regression model: PiecewiseExponentialRegressionFitter is available. See blog post here: https://dataorigami.net/blogs/napkin-folding/churn
  • Regression models have a new method log_likelihood_ratio_test that computes, you guessed it, the log-likelihood ratio test. Previously this was an internal API that is being exposed.
API changes
  • The default behavior of the predict method on non-parametric estimators (KaplanMeierFitter, etc.) has changed from (previous) linear interpolation to (new) return last value. Linear interpolation is still possible with the interpolate flag.
  • removing _compute_likelihood_ratio_test on regression models. Use log_likelihood_ratio_test now.

KaplanMeierFitter by default uses interpolation to calculate survival probabilities
