Regression Slope Test
know this through hypothesis testing as confounders may not test signiﬁcant but would still be necessary in the regression model). • Adding an unimportant predictor may increase the residual mean square thereby reducing the usefulness of the model.

We are testing the null hypothesis H0: “ 0 = 00 1 against the research hypothesis H1: “ 0 6= 00 1. We never get to observe the full population so never get to know 0 and 1 so we have to rely on a sample. We randomly allocate individuals into a treatment group who receives the drug (Di = 1) and a control group that doesn’t (Di = 0). For ...

Hypothesis Testing in the Multiple regression model • Testing that individual coefficients take a specific value such as zero or some other value is done in exactly the same way as with the simple two variable regression model. • Now suppose we wish to test that a number of coefficients or combinations of coefficients take some particular ...
