Good Morning Sir/Ma, I am POPOOLA DANIEL a Forest Biometrician in making from the University of Ibadan, Ibadan Nigeria. Please Sir/Ma I am having issues on performing Non-linear mixed model on R (using maximum likelihood approach). I am trying to input four different measured variables which are basal area, diameter at breast height, Dominant height,quadratic mean diameter as a function for height prediction on equation. But I have not been able to get through with the model. Please I need your candid options on how to go about this. Other useful tips on Codes entering for data analysis in R environment will also be appreciated . Thanks in anticipation to your reply.

(1) Your question is far too vague for anyone to be able to give you a useful response. You should provide a small reproducible example of what you are trying to do and a clear explanation of what problems you are having in trying to do it. (2) Questions about mixed models are better addressed to the "special interest group" R-sig-ME. cheers, Rolf Turner
