WebMay 1, 2016 · For SLA, the meta-analysis strongly confirmed the predicted influence of plant size on the trait–growth correlation. For wood density A area, seed mass and maximum height results were consistent with predictions, but data were limited and additional studies would be helpful for these trait–growth–stage relationships. WebFor a binary logistic main-effects model, logit ( p )=Σ x β , the marginal effect of x is equal to p (1– p) b , where p is the event probability at the chosen setting of the predictors and b is the parameter estimate for x . The binary probit main-effects model is Φ -1 ( p )=Σ x β , where Φ -1 is the inverse of the cumulative normal ...
