Statistics.FTest Method

function FTest(const Data1: TVec; const Data2: TVec; out hRes: THypothesisResult; out Signif: Double; var ConfInt: TDoubleArray; hType: THypothesisType; Alpha: Double): Double;

F Test.

#NameDescription
1Data1First data set from which to compute standard deviation.
2Data2Second data set from which to compute standard deviation.
3hResReturns the result of the null hypothesis (default assumption is that the means are equal).
4hTypeDefines the type of the null hypothesis (left, right and two - tailed).
5Signif(Significance level) returns the probability of observing the given result by chance given that the null hypothesis is true.
6ConfIntReturns the 100*(1-Alpha) percent confidence interval for the mean.
7AlphaDefines the desired significance level. If the significance probability (Signif) is bellow the desired significance (Alpha), the null hypothesis is rejected.

Returns: Double - The F-test statistics.

Remarks:

Performs F-Test by comparing Data1 and Data2 standard deviations.
