WebAn adjustment method that is usually appropriate is Bonferroni; however, it can be quite conservative. Using adjust = "mvt" is the closest to being the “exact” all-around method “single-step” method, as it uses the multivariate t distribution (and the mvtnorm package) with the same covariance structure as the estimates to determine the adjustment. eas in medicina
