| 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?
