WebInstead of considering the x2 and x2^2 terms separately, the "chunk test" is the 2-df test which tests the null hypothesis that the coefficients of those terms are both zero (I believe it's more commonly called something like a "general linear F-test"). The p-value for that test … I'm quite familiar with traditional dummy variable coding - code 1 for presence of … WebFeb 4, 2024 · If the chunk test is significant, then backward elimination, as described in 2, can be carried out to decide if both interaction terms need to be retained or whether one of the terms can be dropped. Also, even if the chunk test is not significant, backward elimination may be carried out to determine whether a significant interaction term can ...
