I am trying to calculate ePCP and Brier scores in R for a mixed-effect binary logistic regression. It cannot seem to find any packages that work for mixed models. I have tried the packages OOmisc and ModelGood, and spent much time searching the web with no success.

I am using the lme4 package to fit the regression.

I would be very grateful for any tips.

  • $\begingroup$ Sorry if it is off topic. I was wondering if anyone knows a way, in R or otherwise, to calculate these./ $\endgroup$

  • $\begingroup$ Try reformulating your question as about the relevant statistical issues & we can re-open it. If you only want to know about what code / package, you could try the r-help listserv, which would be a better option for you anyway. There is also a specialized listserv for mixed models you could try. $\endgroup$ Jun 3 '14 at 14:23

You can just use the predict function, as you would with a regular glm model, there is nothing special about calculating a brier score from a mixed model.
