Hi,  
I want to get individual parameters for subject given the concentration. I used to get that using POSTHOC in NONMEM. what is equivalent to that in PUMAS.  
I have tried with `icoef(model,population,param)` but it did not consider the random effects while estimating individual parameters, just calculated using fixed effects.  
Can someone tell how to do POSTHOC in PUMAS.

What made you conclude that? The command is correct and should give you what NONMEM calls the `POSTHOC` estimates.

I did not know what equivalent command to POSTHOC. So, i just gave a try.

Do you have a fitted pumas model? Let’s say you have it in `fit_result` then you should use `icoef(fit_result)` to get the EBE information included.
