  abstract = {{T}ests of shift in diversification associated with key innovations or directional environmental change can be performed with sister-clade comparisons. {T}his approach is attractive because it does not require detailed phylogenetic information. {I} propose a new likelihood ratio test based on fitting two models of diversification. {I} show how this test differs from a previous likelihood ratio test based on the geometric distribution. {W}ith simulations from a wide range of situations, {I} show that the new test performs much better than this test and the traditional test by {S}lowinski and {G}uyer. {T}he proposed test performs at least as well as the species richness contrast test that has been proposed by several authors in four versions. {A} power analysis with low number of pairs of sister clades showed that the new test could detect a shift in diversification with five or less pairs of sister clades, whereas the diversity contrast test cannot detect any shift in this situation. {T}he former appears as more powerful than the latter, and therefore is recommended when the number of pairs of sister clades is low (less than 10). {A}ll other tests should not be used as the present study showed they lack statistical power and robustness.},
