Hi Phil,

I found an error situation when I tried to use the multidimensional exploratory model with latent regressor.

Here is a test case:

mirt(Science[,1:3], 2, SE = T, SE.type = 'Richardson', method = 'QMCEM', covdata = data.frame(Science[4]), formula = ~Benefit)
Error : Error in rs$r1 * log_itemtrace : non-conformable arrays
