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 variable. Thanks,

That c1 and c1 correspond to ZK. That b2 is -1.11 from the step before? The rest, ZKy1 and ZKy2 I can't place. Please help, Alex
