Re: [R] inconsistencies between HLM and clmm results for the signs for the coefficients

Dear Debbie, Have a look at the vignette of the ordinal package. Look for the equation that defines \eta. And note the minus sign associated with \beta. You'll need to find the equation used in HLM and compare it with the equation from ordinal. Best regards, ir. Thierry Onkelinx Statisticus /

[R] inconsistencies between HLM and clmm results for the signs for the coefficients

I've generated a very simple multilevel ordinal model using HLM software and using the clmm function from the ordinal package in R. The threshold values and coefficients are comparable, however the signs for the coefficients (and only the coefficients; not the thresholds) are opposite (e.g.,
