st: set constraints for coefficients of independents in regression

Subject   st: set constraints for coefficients of independents in regression
Date   Wed, 1 Jun 2011 23:40:01 -0400

When I run a regression, I need to constrain the coefficients of four
independents to be four different values I calculate from previous
regressions.
The constrained coefficient for each independent variable is a
constant value. When I calculate each of these values from previous
regression should I save them as a new variable with a single value
for all the observations or as a vector?
How to use "constraint define" to set the constraints for the
coefficient of each independent?
Thank you!
