who can help me explain this results from SEM?
how to explain this SEM output? what is the meaning of this: like "iteration 0, iteration 1...." and "cons"...?
Fitting fixed-effects model:
Iteration 0: log likelihood = -537.55747
Iteration 1: log likelihood = -508.01999
Iteration 2: log likelihood = -409.70796
Refining starting values:
Grid node 0: log likelihood = -353.36602
Fitting full model:
Iteration 0: log likelihood = -353.36602
Iteration 1: log likelihood = -328.13095
Iteration 2: log likelihood = -322.67416
Iteration 3: log likelihood = -322.55933
