WebSep 7, 2024 · If type is set to 'fdr', the Benjamini-Hochberg procedure to control the false discovery rate is implemented at a tolerance level set to alpha [7]. This procedure is less conservative than the step-wise Bonferroni procedures but will not maintain the FWER. The FDR is maintained where tests are independent or positively correlated.

Bonferroni suggests a simple way of dividing the p-value by the number of tests, known as Bonferroni adjustment for p-value. However, this adjustment is very conservative. In order to decrease false discoveries, it increases the chances of false negatives. top ten marijuana strains
