NLME- number of iterations

["Pravin" <jadhavpr@vcu.edu>]

Hello all,

 

For NLME function in SPLUS, I would like to estimate individual parameters by fixing population estimates. I am not interested in estimating population parameters.

 

Here is a part of NLME code that I am working with. It works fine for the estimation purposes. There are 3 fixed effect parameters(LNCL, LNCLM, LNV) + random variability on 2 parameters (LNCL, LNV) + residual error. I would like to try different combinations of population estimates. Do I fix number of iterations to zero? If yes, how?

 

            nlme.fit<-nlme(log(obscp)~log(dose*exp(-exp(lncl+lndclm*ismale)*time/exp(lnv))/exp(lnv)),

            data="">

            fixed=lncl+lndclm+lnv~1,

            random=lncl+lnv~1|id,

            start=c(log(clf),log(clm-clf),log(v)))

                                   

 

Thank you very much,

 

Pravin
