i am performing two group t test of the size of a brain structure. however, the size of the structure is affected by age and total brain volume. i used anova brainstructure group c.age c.tbv. during the result reporting meeting, one superver teacher suggested i should perform t test with covariate. with simple t test. that is impossible. i think glm can. but i don't know how to do that. can anyone help me with this?
i also find the content "Another example of why we should ditch the old terminology and just use general linear models! Forget t tests, ANOVA, ANCOVA, and regression. GLM!". so i am quite motivated to learn glm, though i wasn't taught to do it in school, let alone with stata. i learned stata by myself. so my knowlege about stata is not completely.
