Dear all, I want to estimate a nonlinear mixed effect model using nlme package or lme4. How can I specify this
y=exp(B'X)/(1+exp(B'X)). the same model can be obtained with logit(y)=B'X but I have many value of 1 in y logit(1)=Inf. Justin BEM BP 1917 Yaoundé Tél (237) 99597295 (237) 22040246 [[alternative HTML version deleted]]
