Dear Statalisters,
we are faced with a constraint problem for sureg.
There is an equation system of n equations.
Y1 = alpha1 + beta1 * x1
Y2 = alpha2 + beta2 * x2
...
Yn = alphan + betan * x3
The theory states that all betai are the same.
How can we restrict it in STATA with a constraint?
We are using STATA 8.2
With many thanks and Happy-Christmas-Wishes,
Stephan
PS: Sorry if it is posted twice.
