SEM GFI

Dear Vinay and Burt,

I didn't see Vinay's original posting -- sorry about that.

Vinay: There's still not enough information here to tell why the results are different, and posting in HTML makes the code very hard to read. 

To elaborate slightly: You don't provide the data, so it's not possible to replicate your results. You also don't show the command or results from SAS, so it's not possible to know how the results differ. Your original message seems to imply that the results are identical accept for the value of GFI and one coefficient standard error. That seems unlikely. My guess: you inadvertently fit different models in SAS and sem.

Additionally, you'd probably find it easier, and less error prone, to specify the model in sem() using specifyEquations() rather than specifyModel(), as the message printed by the latter tells you.

I hope this helps,
 John
