Hello all,
I am having the same question as this previous post. Any insight please?
I ran a flexible full factorial design on longitudinal data with 2 factors (subject = 1 group, time = Pre- and Post intervention) and 2 covariates (clinical scores at Pre and Post). What contrast should I use to analyze the effect of each covariate on the Pre-to-Post structural changes ? Is a [-1 1 1 0] contrast models the effect of covariate 1 on the pre-to-post changes ?
Thank you,
Best regards,
Nabila
