2012/3/12 -This modified sequentially rejective Bonferroni (MSRB) procedure will never be less powerful (and typically will be more powerful) than the SRB procedure.

The multiple comparison procedure should be based on the set of values of each mean difference or contrast divided by the square root of its estimated variance.

We first note that Shaffer's powerful sequentially rejective procedure is equivalent to Peritz's (1970) closed testing scheme when a natural relation holds ...
