Data | Sliding windows | 2Δℓ | 2Δℓ | |
Statistic a | p-value | (M1a-M2a) | (M7-M8) | |
Mouse-rat | 19 | 0.096 | 2.24 | 2.39 |
Human-dog | 18 | 0.007** | 8.18* | 9.08* |

The test statistic in the sliding window analysis is the number of windows in which ωˆ>1. The window size is 100 codons, and the offset is 10 codons. In the LRTs, the test statistic 2Δℓ is the log likelihood difference between the null and alternative models.
: significance with p<5%.
: significance with p<1%.
