I used a multiple regression analysis to show correlation with two covariates [A B].
When I use the contrast[1 0] , am I looking at a +ve correlation with covariate A only.
When I use the contrast[1 -1] , am I looking a a map of +ve correlation with covariate A minus
correlation with covariateB. Or is it simply a +ve correlation with A and a -ve correlation with B ?
Any clarification would be greatly appreciated.
