st: Inequality constraints in cnsreg

["Herve STOLOWY" <stolowy@hec.fr>]

Dear Statalisters:

I am using Stata 11.1

I would like to use cnsreg to create the following constaints:

Y X1 X2 X3 X4
constriant 1 X2 > X1
constraint 2 X4 > X3

I have read the threads which existed a few years ago and a recent one
on the topic of inequality constraints
(http://www.stata.com/statalist/archive/2010-04/msg01437.html).

I have also read the answer from Marteen Buis and his suggested solution
(http://www.stata.com/support/faqs/stat/intconst.html).

I do not understand very well the suggested solution and I am not
trained in programming.

Consequently, my question is the following: is there a "not too complex"
solution to get the constraints I need? 

Best regards

Hervé Stolowy
