Hi,
I am non-expert SEM user. I am trying to run a CFA with the EQS 6.2 program. After creating the EQS input file, I tried to run EQS but in the output file I found the following sentence:
*** ERROR *** VARIABLE NUMBER 1, A DEPENDENT VARIABLE, EXCEEDS THE NUMBER OF VARIABLES READ. and so on for all other variables. Could you help me to solve the problem?
Thanks

EQS 6.2 - error: variable exceeds the number of variable read

Hi,
can somebody help me to solve the problem? Is there anybody who is an expert in using EQS?
Thanks
I'm not an EQS expert, but that sounds like a data reading problem. Is there a way to verify that EQS is reading in your data correctly?
Thanks mhunter,
this could be the problem. It is the first time I use SEM and it is difficult for me to establish what's wrong with the input file or in the data reading.
Here attached you can find my input file. The aim is testing for the factorial validity of scores from a measuring instrument with a Second-order CFA Model. Are you familiar with this? For writing the input file I used suggestions from Barbara Byrne's book entitled "Structural Equation Modeling with EQS"
Thanks

What do the first few lines of the 'g:\project\data.ess' file look like? Are they comma separated values (csv)? Tab delimited?
