WebOct 31, 2008 · A simple method to control the family-wise error rate is the Bonferroni correction, which adjusts the Type 1 error (a) by the total number of tests (a/n). The Bonferroni correction can use the actual number of tests performed (i.e. SNPs genotyped) or a theoretical value based on the total number of tests possible (i.e. all SNPs).
