Palaszewski, Bo2011-02-222011-02-221994-05-010349-8034http://hdl.handle.net/2077/24605We consider hypothesis testing problems arising in e.g. the context of comparing k treatments with a control. The case of equi-correlated estimates is mainly discussed, although also unequal correlated estimates (e.g. unequal sample sizes for the treatments, when compared to a control treatment) are mentioned briefly. So called step down test procedures are compared with step up test procedures, with respect to power functions. Comparisons of rejected null hypotheses are also performed. No practical differences in performances between step up and step down test procedures could be found for finite sample sizes.18engMultiple level of significancestep up test procedurestep down test procedurepower comparisonsproduct correlation structurefinite sample sizesMonte Carlo simulationText
