• Estimates of covariance between traits were derived using vari- ance estimates of each pair of traits and of their sum by analogy with x ,y = 1 2 (x2+ y - x2 - y2 ). (Fries, Ericsson, 1998)
• Our model (Equation 1) does not assume that interaction among kin differs from that among non-kin, although the model extends by analogy to incorporate that phenomenon; see the discussion.] (Bijma, Muir, Van Arendonk, 2007)
• By analogy it was easily observed that the control of the number of factors was required for the control of the expected prediction error by the fitted model. (Akaike, 1987)
