Hi,
I have a simulation problem.
Usually, what I've seen done in simulations is to change
values in independent variables and see their result on the
(predicted dependent variable).
Ex:
reg GDP pop invest
predict gdphat
su gdphat
replace pop =pop * 1.03 /* 3% growth of
population*/
predict gdphat2
su gdphat2
g diff = gdphat - gdphat2 /*Measure of the
impact of the population growth */
Now, here is my question:
Suppose I want to double my GDP ?
I am interested in how my independent variables will change (in their
coeffcients and/or in their observations ???)
to meet the new values of GDP.
I guess I am facing a constraint problem but do not know how to do this in
Stata.
How can I do that?
Best regards.
Amadou.
