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. WebJul 1, 2003 · A method for controlling the familywise error rate combining the Bonferroni adjustment and fixed testing sequence procedures is proposed. This procedure allots Type I error like the Bonferroni adjustment, but allows the Type I error to accumulate whenever a null hypothesis is rejected. how much opal is mined per year
