just fix the factor loading of an indicator variable to one and the error variance to zero. Then, the manifest variable will be equal to the latent variable. Do you nee help with the syntax?
Its related to your research question or hypothesis.If you want to get a model from your data, first you should check exploratory factor analysis with SPSS, then do a confirmatory factor analysis with LISREL.
Is this method applicable to ordinal variables as well? My issues is with an ordinal dependent variable. If I try to define this ibserved variable as a dependent to an independent latent variable, it takes it as another indicator variable to that latent variable. I have tried to avoid this problem by creating a single (ordinal) indicator latent variable as the dependent variable. The model works, but is this the right approach?
