After run an analysis and produce the estimated coefficients of the regression model from an 24 item set and four dimensions, I’m stuck in trying to obtain the R-square values for each of the dimensions of the model. I wonder if you could send me the formulae, or any advice to compute these determination coefficients in ConQuest or any collateral software as it is in the Conquest manual on chapters of latent regression (both unidimensional and multidimensional).

Thanks for any advice,

Luis
