Hi! I am trying to do a multiple regression but when I try to do it, I don't get any of the p-values, st errors or t values. Please let me know what I am doing wrong! Thank you so much!

All of my variables are binary and I am using the following code:

regress V162034a V161345 V161320 V161157



Source | SS df MS Number of obs = 6
-------------+---------------------------------- F(3, 2) = .
Model | .833333333 3 .277777778 Prob > F = .
Residual | 0 2 0 R-squared = 1.0000
-------------+---------------------------------- Adj R-squared = 1.0000
Total | .833333333 5 .166666667 Root MSE = 0

------------------------------------------------------------------------------
V162034a | Coef. Std. Err. t P>|t| [95% Conf. Interval]
-------------+----------------------------------------------------------------
V161345 | -5.07e-17 . . . . .
V161320 | 2.03e-16 . . . . .
V161157 | -1 . . . . .
