Quizplus · Accepted Answer

A partial F test on the subset of the appropriate coefficients would be the best choice. This test specifically tests for the difference between the curves for cove and non-cove properties, while controlling for other factors in the regression model. A full F test for the entire regression model would not specifically target this comparison, and a t-test on each coefficient or subset of coefficients would not account for the additional factors in the model.
