Dear all,
Your're right. It's a matter of convention.
I've been thought in school of "independent" and "dependent" variables.
As long as I know what is what, it is not a big issue to me.
Coming back to my initial problem, I think I want to solve something like:
aX + bY + cZ = d
where a, b, c are coefficients issues from the regression (my "betas" if I can
say so) and X, Y, Z are vectors of observations (in my case POP and INVEST).
d is equal to 2, if I stick to my previous problem of doubling my GDP.
Is there a way to solve such an equation in stata?
Best regards.
Amadou.

Please respond to

One convention that I like, is that if a variable is set by design in a
prospective study, it is "independent". If a variable is observed and is the
measure upon which one desires to do statistical inference, it is a
"dependent variable". If is observed or measured in conjuntion with the
dependent variable, but is not a "dependent" variable it is a "covariate".

I, too, like terminology such as response/predictor/covariate. But we
usually use "outcome" in place of "response".
Then we often analyze family economic data, and we find ourselves in the
paradoxical situation where our outcome is income.
