Question: Regression without a constant, suppose that you estimate a multiple regression first with then without a constant. Whether the R2 is higher in the second

Regression without a constant, suppose that you estimate a multiple regression first with then without a constant. Whether the R2 is higher in the second case than the first will depend in part on how it is computed. Using the (relatively) standard method R2 = 1 − (e' e/y'M0y), which regression will have a higher R2?
