F-Distribution

Implements the F-distribution used for an ANOVA or for the comparison of the fit of two nested regression models. In both cases, the test statistic follows a F-distribution. NestedModel is used to compare the fit of two regression models, where one model contains the independent variables of the smaller model as a subset. Then, one can use ANOVA to determine whether more variance can be explained by adding more independent variables. In the class ANOVA, the number of independent variables of the smaller model is set to \(1\) in order to match the degrees of freedom and we obtain a one-way ANOVA.
