Fixed sequence procedure
WebComputation of adjusted p-values for commonly used multiple testing procedures based on univariate p-values (Bonferroni, Holm, Hommel, Hochberg, fixed-sequence and Fallback procedures), commonly used parametric multiple testing procedures (single-step and step-down Dunnett procedures) and multistage gatepeeking procedure. Usage WebWe develop a procedure called the “fallback procedure” to control the familywise error rate when multiple primary hypotheses are tested. With the fallback procedure, the Type I error rate (α) is partitioned among the various hypotheses of interest.
