I'm using the fwdmsa package to identify deviant cases in a Mokken scale analysis. I've run into a problem., separate from the one I posted previously. The problem comes with items that are "easy" by IRT standards. A good scale should include a range of difficulties; yet when I include "easy" items in a forward search I continuously run int...

I'm using the fwdmsa package to identify deviant cases in a Mokken scale analysis. I've run into a problem. When I use scales comprising a few items, iI tend to get an error: Error in y[order(res[-msamp])][1:(length(samp) + 1 - length(msamp))] : only 0's may be mixed with negative subscripts I understand that the error is triggered when the algorithm...
