Test

[Racha]

Hi all,
I have two questions:
First: I estimate a demand system and i compute the elasticities. How to test the significance of the elasticities? Test command require proc model and i didn't use it for the computation

Second:I tried to estimate system of equations using ITOLS command i got this error message:
ERROR: Parsing error generating code.
The same program is run by my professor and he got results!!
What is this message about?

Thanks
