Is there any possibility to get the estimated values (listed for every participant) of a specific latent variable in R or Mplus?
I assume you are using lavaan in R. How about lavPredict(): https://www.rdocumentation.org/packages/lavaan/versions/0.6-6/topics/lavPredict
Hi Robin and Roland,
I assume that there are not really possibilities to do that. Yes, you can estimate factor scores (or latent variable scores) but they are....well estimates and introduce error into the scores (the "factor indeterminacy problem"). The only goal that factor scores fulfill is that they reproduce the factor correlation matrix. But really values of individuals? I don't think there is a method to do that.
