Hey,
I'm unsure if I understood the concept of definition variables right. So I have an ordinal manifest and I would like to add covariates that are calculated outside of mxData which I use to calculate the models (i.e. covariates are calculated using a bigger sample, but only a smaller sample is used for analysis). With continuous variables, I would know how do it (simply performing a linear regression beforehand with the bigger sample and only using the residuals in the actual analysis with the smaller sample). How can I do this with definition variables? Or is it even possible?
Thanks in advance!
P.S. I'm using path specification
