I am trying to estimate a fairly simple and identical CFA model on a set of different countries. This is being done separately for every country.
The observed variables are measured and coded exactly the same in all cases (that is for all countries), but for whatever reason my degrees of freedom in the "Chi-square Test of Model Fit for the Baseline model" output section differ for some countries (ranging from 3 to, most frequently 5, if this is relevant). My degrees of freedom for the final model are always the same though and = 1, as would be expected. The fit of the separate models is adequate and quite nice - really no surprises here.
I am curious about this discrepancy in the "Baseline model" output and where it comes from. Does it necessarily point at any problem with the models?
I just upgraded to version 6 and the problem seems to be solved. Now the DFs in the baseline model are equal to the number of free parameters = 6. All other model fit estimates remain the same. Not sure what was the reason of the problem in the previous version though. Can it possibly result from the fact that the CFA model I am estimating includes 3 categorical (2- 3- and 4- point scale) and 1 continious (11-point scale) variable?
