WebI also found that the algorithms used in fcrmrmr and fsrmrmr are consistent, but according to the literature referenced by this algorithm, MIQ is a better choice for discrete/categorical features, while FCQ (Fisher's criterion quotient) is preferred for continuous features [1]." Common examples of the use of F-tests include the study of the following cases: • The hypothesis that the means of a given set of normally distributed populations, all having the same standard deviation, are equal. This is perhaps the best-known F-test, and plays an important role in the analysis of variance (ANOVA). • The hypothesis that a proposed regression model fits the data well.
