Bonferroni-holm test
WebThe Bonferroni test is a statistical comparison test that involves checking multiple tests limiting the chance of failure. It is otherwise known as the Bonferroni correction or Bonferroni adjustment. The test allows for the comparison of several variables to avoid false data appearing statistically significant.
