topic Constraints in Lineair regression in Mathematical Optimization, Discrete-Event Simulation, and OR https://communities.sas.com/t5/Mathematical-Optimization/Constraints-in-Lineair-regression/m-p/7342#M172 Hi,<BR /> <BR /> I'm a student working on my masters thesis. I'm using SAS to detect the maximum R² for several regressions. However, the coefficients on my independent variables must sum to one and must all be &gt;=0. Does anyone know how to implement this from Lineair regression's analysis in SAS?<BR /> <BR /> <BR /> Thank you so much!<BR /> <BR /> Kristof Sat, 08 Mar 2008 20:48:44 GMT deleted_user 2008-03-08T20:48:44Z Constraints in Lineair regression https://communities.sas.com/t5/Mathematical-Optimization/Constraints-in-Lineair-regression/m-p/7342#M172 Hi,<BR /> <BR /> I'm a student working on my masters thesis.
