The ?Help? entry for ?regress? includes:
?Note When computing statistics, X should include a column of 1s so that the model contains a constant term. The F statistic and its p value are computed under this assumption, and they are not correct for models without a constant. The R2 statistic can be negative for models without a constant, indicating that the model is not appropriate for the data.?
Did you do that?
