    <subfield code="a">&lt;p&gt;This release adds the &lt;em&gt;ties&lt;/em&gt; argument to &lt;a href="https://scikit-survival.readthedocs.io/en/latest/generated/sksurv.linear_model.CoxPHSurvivalAnalysis.html#sksurv.linear_model.CoxPHSurvivalAnalysis"&gt;sksurv.linear_model.CoxPHSurvivalAnalysis&lt;/a&gt; to choose between Breslow's and Efron's likelihood in the presence of tied event times. Moreover, &lt;a href="https://scikit-survival.readthedocs.io/en/latest/generated/sksurv.compare.compare_survival.html#sksurv.compare.compare_survival"&gt;sksurv.compare.compare_survival()&lt;/a&gt; has been added, which implements the log-rank hypothesis test for comparing the survival function of 2 or more groups.&lt;/p&gt;
Enhancements
&lt;ul&gt;
&lt;li&gt;Update API doc of predict function of boosting estimators (#75).&lt;/li&gt;
&lt;li&gt;Clarify documentation for GradientBoostingSurvivalAnalysis (#78).&lt;/li&gt;
&lt;li&gt;Implement Efron's likelihood for handling tied event times.&lt;/li&gt;
&lt;li&gt;Implement log-rank test for comparing survival curves.&lt;/li&gt;
&lt;li&gt;Add support for scipy 1.3.1 (#66).&lt;/li&gt;
&lt;/ul&gt;
Bug fixes
&lt;ul&gt;
&lt;li&gt;Re-add &lt;em&gt;baseline&lt;em&gt;survival&lt;/em&gt;&lt;/em&gt; and &lt;em&gt;cum_baseline&lt;em&gt;hazard&lt;/em&gt;&lt;/em&gt; attributes to &lt;a href="https://scikit-survival.readthedocs.io/en/latest/generated/sksurv.linear_model.CoxPHSurvivalAnalysis.html#sksurv.linear_model.CoxPHSurvivalAnalysis"&gt;sksurv.linear_model.CoxPHSurvivalAnalysis&lt;/a&gt; (#76).&lt;/li&gt;
