| # | Signature | Description |
|---|---|---|
| 1 | function WilcoxonSign(const Data1: TVec; const Data2: TVec; out hRes: THypothesisResult; out Signif: Double; var ConfInt: TDoubleArray; const hType: THypothesisType; const Alpha: Double): Double; | Performs two-sample Wilcoxon Signed-Rank test by comparing Data1 and Data2 medians. |
| 2 | function WilcoxonSign(const Data: TVec; const Median: Double; out hRes: THypothesisResult; out Signif: Double; var ConfInt: TDoubleArray; const hType: THypothesisType; const Alpha: Double): Double; | One or two-sample Wilcoxon signed rank test. |
Overload 1: function WilcoxonSign(const Data1: TVec; const Data2: TVec; out hRes: THypothesisResult; out Signif: Double; var ConfInt: TDoubleArray; const hType: THypothesisType; const Alpha: Double): Double;
Performs two-sample Wilcoxon Signed-Rank test by comparing Data1 and Data2 medians.
| # | Name | Description |
|---|---|---|
| 1 | Data1 | First set of data from which to compute the median. |
| 2 | Data2 | Second set of data from which to compute the median. |
| 3 | hRes | Returns the result of the null hypothesis (default assumption is that the means are equal). |
| 4 | hType | Defines the type of the null hypothesis (left, right and two - tailed). |
| 5 | Signif | (Significance level) returns the probability of observing the given result by chance given that the null hypothesis is true. |
| 6 | ConfInt | Returns the 100*(1-Alpha) percent confidence interval for the mean. |
| 7 | Alpha | Defines the desired significance level. If the significance probability (Signif) is bellow the desired significance (Alpha), the null hypothesis is rejected. |
Returns: Double - The Wilcoxon W statistics.
Remarks:
The routine tests the null hypothesis that Data1 and Data2 have equal median value.

Overload 2: function WilcoxonSign(const Data: TVec; const Median: Double; out hRes: THypothesisResult; out Signif: Double; var ConfInt: TDoubleArray; const hType: THypothesisType; const Alpha: Double): Double;
One or two-sample Wilcoxon signed rank test.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Data | TVec | |
| 2 | Median | Double | |
| 3 | hRes | THypothesisResult | |
| 4 | Signif | Double | |
| 5 | ConfInt | TDoubleArray | |
| 6 | hType | THypothesisType | |
| 7 | Alpha | Double |
Returns: Double
Remarks:
Performs one-sample Wilcoxon Signed-Rank test by comparing Data median value with given Median. The null hypothesis is that Data median is equal to Median.
