In the linear equation, Y = A + BX, B represents the slope of the line relating the dependent variable Y to the independent variable X. A t-test can be used to test whether B = B0 versus B ≠ B0.

      As in simple linear regression, under the null hypothesis t 0 = βˆ j seˆ(βˆ j) ∼ t n−p−1. We reject H 0 if |t 0| > t n−p−1,1−α/2. This is a partial test because βˆ j depends on all of the other predictors x i, i 6= j that are in the model. Thus, this is a test of the contribution of x j given the other predictors in the model.
