Remarks

Use the FTest class to compare the variances of two samples.

In many statistical models, the contribution of a variable to the model is measured by comparing the variance explained by the variable to the residual variance in the model. The higher the ratio of the two variances, the more significant the contribution of the variable is.

The data for the FTest can be provided in two ways for each variable: either by supplying the sample as a NumericalVariable, or by supplying only the parameters: the variance and the degrees of freedom of the sample. Sample1 represents the sample for the numerator while Sample2 represents the sample for the denominator. Any mixture of samples and parameters is allowed.
