The R2 = 1 and the residual sum of squares = 0 says everything: you have the same variable (or linear combination of variables) on the left and right hand side of the equation.

Dear Statalisters,
I ran the following model in stata and spss and got different results.
Obviously, there are degrees-of-freedom problem in this dataset, but I wonder whether this is the reason I got very different results.
Here is the output:
