Error In Cels With Individual Nonmem

If not, how do you compute the Log-Likelihood??

Of course I think in terms of MCPEM but I cannot understand how you can combine an exponential error with additive and compute a log-likelihood. best regards, Joost DeJongh Dr. Message issured from estimation step at initial obj function evaluation. He has worked at Genzyme, Hoechst Marion Roussel, Eli Lilly, and Quintiles.

An individual residual is the difference between a response and its individual-specific prediction, (when there are L2 records, the response may be multivariate, and the residual will be a vector difference). If anyone can help, it'll be much appreciated. He has served or currently serves on the editorial boards for the Journal of Clinical Pharmacology, Pharmaceutical Research, Journal of Pharmacokinetics and Pharmacodynamics, and The AAPS Journal. I had wanted to combine the proportional errors (eps 1,3 & eps 5,7) but wanted to leave the additive residual errors individually.

  1. Since the "weight" for the sum of squares is the error variance, and this appears in the denominator of the calculation of the sum of weighted squared deviations, you're getting an
  2. When you assume exponential error variance, the data are log-transformed and the error model is then assumed to follow a constant variance model.
  3. In this case, you have proportional error model.
