Multivariate regression hypothesis testing
WebAs 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. Web25 sept. 2015 · I show a version of the formula here: Testing for moderation with continuous vs. categorical moderators. In a non-linear context (e.g., a logistic regression model), a likelihood ratio test can be used. More generally, testing multiple parameters at the same time is called a simultaneous test or a chunk test.
