Hi all,
I have a scale composed of 15 variables (items in a 5-point likert scale) that correspond to 3 factors/domains. How do I run CFA using gllamm. Sophia, who developed gllamm, suggested it could be used for CFA in the statalist but was not specific and I am struggling to define the factors and run the analysis. I've read gllamm's manual, but still could not figure out how to do it.
My data:
Suppose the variable names are x1-x15 and the factors are f1 f2 and f3.
f1 corresponds to variables x1-x5
f2 corresponds to variables x6-x10
f2 corresponds to variables x11-x15
I tried using the eq syntax to define the factors (equations) using the following syntax:
eq f1: x1-x5
eq f2: x6-x10
eq f3: x11-x15
but where do I go from here? I'll not even post all my attempts.
Any ideas?
