I’m dipping my toes into the
brms package, currently working with ordinal regression. Unfortunately, I’m experiencing a lot of crashes. Here is a screen dump from the latest one:
This occurred when applying
fitt2is the fitted model as conveniently shown in in the screen dump after crashing, but previously the same occurred just after
fitt2was fitted. Not sure if it’s related, but I consistently get the following warning message after fitting:
Warning message: In system(paste(CXX, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) : 'C:/rtools40/usr/mingw_/bin/g++' not found
Info about the data: The data is questionnaire data with ordered responses (5 levels) regarding farmers’ perceptions of innovation needs in response to wildlife damage. 222 farmers (
ID) were asked 6 questions (
Q), and the data frame
DF contains 1332 observations. These first two analyses are merely trying to rank the responses to the questions by their coefficients, with (
fitt2) and without (
fitt) accounting for farmer
ID random effects.
Any ideas what’s going on?
