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.

	Hello all!

 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
