Thank you very much for your response. I have to keep on searching and finding a means or doomed in it. Am working in academic context as you suggested. Once more, thanks. ... View more

Good day Chris, I have a serious problem with my research work. Am working on Intrinsically Nonlinear Split-plot Design Modelling.  I am stock in the analyses. I am to compare the OLS and EGLS estimates. Also for the EGLS, the variance components are to be estimated using ANOVA, MLE and REML. Finally the residuals from each fit is need for further comparison. I am using, Weibull, Gompertz, Johnson-Schumacher, Bertalanffy-Richards and Chapman-Richards functions to model split-plot experimental design nonlinearly.   Please assist me with the possible sample of SAS %NLINMIX code. Attached is the detailed models. This is my email: ikwuoche8@gmail.com. I will be glad if you send me your email so I can forward the details of the models.  Please assist me, thanks.   David, I.
