Hi dear all, 
I have just done a constrained regression -cnsreg- to fit a Cobb-Douglas production function. As, there was no R-squared provided, I tried to calculate it using usual formula, explained sum of squares over total sum of squares. I got a result that is above 1. So, I ask the questions below: 
1- Is there a reason for which there is no provided R-squared for the command -cnsreg- ?
2- Could the result that I got be  possible? 
Thanks for your contributions. 
Fo Kodjo Aflagah.
