hi,

i am a novice in using eViews, but i need urgent help with estimating this:

logYt=b0+b1log(X1)t+b2log(X2)t+b3log(X3)t+ut


so i enter it into quick-estimate equation like this, with LS principle:
log(y) c log(x1) log(x2) log(x3)

but it comes up with the error:
"insufficient number of estimations"


thanks in advance

I'm assuming it actually says "insufficient number of observations". Which is exactly as it says - you do not have enough valid observations to perform the regression. Do you have a lot of non-positive numbers in your data?

Hi,

I'm trying to run a big system including 320 equations simultaneously; I think I entered the related data correctly, however, once I try to estimate the system, I faced many errors such as “unmatched parentheses” and likewise “syntax error”, please look at the following equation which is the first equation of the mentioned system, your comments definitely will be helpful,
