Testing for simultaneous equations. Insufficient observation

[pippa9013]

Hi,

I keep getting an error message saying there are insufficient observations. How many observations are needed for testing in eviews? Do I have too few or have I done something wrong in my workfile?

I am trying to test as simultaneous equations

dependent variable = ser01, ser02 ser03 ser04 ser05 ser06 ser07 ser08 c

dependent variable = ser02, ser01 ser04 ser09 ser05 ser08

I have tried to test the first one alone but it has not worked

Perhaps you could provide more details as to what exactly you are doing?
