Declaration
Procedure ChiSquareTest(Data: TVec; Sigma: TSample; out hRes: THypothesisResult; out Signif: TSample; out ConfInt: TTwoElmReal; hType: THypothesisType = htTwoTailed; Alpha: TSample = 0.05);
| Parameter | Description |
|---|
| hRes | Returns the result of the null hypothesis (default assumption is that the means are equal). |
| hType | Defines the type of the null hypothesis (left, right and two - tailed). |
| Signif | (Significance level) returns the probability of observing the given result by chance given that the null hypothesis is true. |
| ConfInt | Returns the 100*(1-Alpha) percent confidence interval for the mean. |
| Alpha | Defines the desired significance level. If the significance probability (Signif) is bellow the desired significance (Alpha), the null hypothesis is rejected. |
Description
Performs Chi-Squared test by comparing sample standard deviation with Sigma.
