WebJul 29, 2014 · In principle, we can obtain constrained linear regression estimates by modifying the list of. independent variables. For instance, if we wanted to fit the model. and constrain β 1 = β 2 , we could write. mpg = β 0 + β 1 price + β 2 weight + u. mpg = β 0 + β 1 (price + weight) + u. and run a regression of mpg on price + weight.

WebIn STATA, we need to run regression (2). Then, test the hypothesis, 1- 2 = 0. III. Constrained regression: If we fail to reject the null hypothesis that 1- 2 = 0. Then, we can try to run regression (2) constraining 1= 2. The STATA command is cnsreg. If we rejected the hypothesis, then we have no grounds to run the constrained regression.
