Statistics::FTest Function

double FTest(TVec *Data1, TVec *Data2, THypothesisResult &hRes, double &Signif, DewArray<double> &ConfInt, THypothesisType hType = THypothesisType::htTwoTailed, double Alpha = 0.05);

F Test.

#NameTypeDescription
1Data1TVec *First data set from which to compute standard deviation.
2Data2TVec *Second data set from which to compute standard deviation.
3hResTHypothesisResult &Returns the result of the null hypothesis (default assumption is that the means are equal).
4Signifdouble &(Significance level) returns the probability of observing the given result by chance given that the null hypothesis is true.
5ConfIntDewArray<double> &Returns the 100*(1-Alpha) percent confidence interval for the mean.
6hType = THypothesisType::htTwoTailedTHypothesisTypeDefines the type of the null hypothesis (left, right and two - tailed).
7Alpha = 0.05doubleDefines the desired significance level. If the significance probability (Signif) is bellow the desired significance (Alpha), the null hypothesis is rejected.

Returns: The F-test statistics.

Remarks:

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