Dear Marcos, I don't see why you can't specify a MIMIC model using sem(), though you might have to supply your own start values. When I have a chance, but possibly not today, I'll check.

I want to estimate parameters in a MIMIC model. I have one latent variable (ksi), four reflexive indicators (y1, y2, y3 and y4) and four formative indicators (x1, x2, x3, x4). Is there a way to do it in R? I know there is the SEM library, but it seems not to be possible to specify formative indicators, that is, observed exogenous variables which causes the latent variable.
