TABLE 2.

Bayesian information criteria (BIC, smaller is better, gray rows) and Bayesian information criterion weights (BICw, interpreted as percentage of explained variance, white rows) for different evolutionary OU models that assume either Brownian motion (BM), no adaptive shifts (k ₀ = 0), or a maximum of three shifts (k ₀ = 3)
