A likelihood ratio test for hybridization under the multispecies coalescent

HIGHLIGHTS

• What: The authors propose a new method for detecting hybridization and quantifying the extent of hybridization. The authors propose to test the hypothesis above using a LRT, which has well-established statistical properties in general contexts (Wilks, 1938). Even when the nucleotide substitution model is misspecified, type I error rates were reasonably controlled by the LRT for CIS data, while HyDe tends to be a conservative test in some cases . The authors develop the likelihood for a 4-taxon network under JC69 and the multispecies coalescent model.
• Who: Coalescent and colleagues from the Center for . . .
