Note: −2LL = negative log-likelihood; df = degrees of freedom; AIC = Akaike information criterion; Compare = the comparison model for the log-likelihood ratio test; Set transmission factors means constraining beta to equal 1.0. The Ai and Ei entries represent the tests of the genetic and environmental innovations. The At and the Et entries represent the tests of the transmission parameters.
