...on for lmer, I used the following to get predicted values (thanks to a post by John Maindonald (I'll attach his post below)): model4 <- lmer (y~time + (1|blc/instar),family=binomial(link="probit")) summary(model4) b <- fixef(model4) X <- (model.matrix(terms(model4),zerotest)) hat <- X%*%b pxal <- pnorm(hat) # probit link, for logit it would be: pval <- exp(hat)/(1+exp(hat)) pval Once I get the pval, I see where the 0.5 predicted value lies and I adjust the x's in zerotest to be more detailed in that range, eg. x: 1-420hours, I see that 0.5 is in...
