/Title:
/The Sequential Rejection Principle of Familywise Error Rate Control/

Abstract:
/We present a general sequentially rejective multiple testing procedure 
for multiple hypothesis testing. Many well known familywise error (FWER)
controlling methods can be constructed as special cases of this 
procedure, among which are the procedures of Holm, Shaffer and Hochberg,
parallel and serial gatekeeping procedures, modern procedures for 
multiple testing in graphs, resampling based multiple testing
procedures, and even the closed testing and partitioning procedures. It 
is possible to prove that sequentially rejective multiple testing
procedures strongly control the FWER if they fulfill simple criteria of 
monotonicity of the critical values and weak FWER control in each single
step. The sequential rejection principle thus gives a novel theoretical 
perspective on many well-known multiple testing procedures, emphasizing
the sequential aspect. Its main practical usefulness is for the 
development of multiple testing procedures for null hypotheses, possibly
logically related, that are structured in a graph. We illustrate the 
general procedure with many examples of graph-based and other procedures.
