<t>2 options really,like what dimitris said, t-stat = [beta1 - 1 (Ho)]/SE (beta1), instead of the usual (beta1-0)/SEanother way is to rearrange your model. try to make your model, Y = beta0 + beta1*X + einto:- (Y-X) = beta0 + (beta1 - 1)*X + e, that way you may use the normal t-stat formula.most sof...
