0.17.1
- adding bottleneck as a dependency. This library is highly-recommended by Pandas, and in lifelines we see some nice performance improvements with it too. (~15% for
CoxPHFitter) - There was a small bug in
CoxPHFitterwhen usingbatch_modethat was causing coefficients to deviate from their MLE value. This bug eluded tests, which means that it's discrepancy was less than 0.0001 difference. It's fixed now, and even more accurate tests are added. - Faster
CoxPHFitter._compute_likelihood_ratio_test() - Fixes a Pandas performance warning in
CoxTimeVaryingFitter. - Performances improvements to
CoxTimeVaryingFitter.
