Dear nmusers,
I have a big doubt. When I used the bootstrap to evaluate my model, I
had some bugs. In my code I use IGNORE statements based on FLAGS for
some outliers. I don't know if I remove these IGNORE statements, the
bootstrap will run well. Can you give me some suggestions???

Great, many thanks for your suggestions, I will definitely try them out.

I have just run a bootstrap analysis on my final Pop PK model using NONMEM 7.2
with PDx-Pop 5. My model has 7 Thetas in it and when I come to evaluate the
output from the bootstrap in R the Theta histograms are plotted in a 3x2 matrix
in an R window, and the plot for Theta 7 seems to overwri

Bootstrap procedure vary only the new data. The information in priors is
still the same. Therefore, results will be as dependent on the priors as
the parameter estimates of the final model. When the priors are strong

First, accept my humble excuse - I can't share any code for this example.
