Subject: st: Bonferroni-holm
dear statalist,
I have found In a paper with the similar methodology with ours that for correction of multiple comparisons, authors have applied bonferroni-holm correction. To explain the analysis in short, they have several dependent variable (subcorticalgray matter region
volumes) and three groups of diagnosis, intracranial volumes,age and sex as predictor variables.they have fitted a GLM for each region volume as the dependant variable seperately, then F test was preformed and subsequently contrast analysis. but for multiple comparison they first corrected for the omnibus test and then correction for pairwise comparison for each GLM that survived the first round of correction was performed. Can you please enlighten me with this correction procedure more in detail.
yours,
Sadjjad Riahi
