Return Value
A double array of length 10 containing statistics.Remarks
The statistics are as follows:
| Row | Statistics |
|---|---|
| 0 | Wilcoxon W statistic (the sum of the ranks of the x observations) adjusted for ties in such a manner that Wis as small as possible |
| 1 | 2 x E(W) - W, where E(W) is the expected value of W |
| 2 | probability of obtaining a statistic less than or equal to min{W, 2 x E(W) - W} |
| 3 | W statistic adjusted for ties in such a manner that Wis as large as possible |
| 4 | 2 x E(W) - W, where E(W) is the expected value of W, adjusted for ties in such a manner that W is as large as possible |
| 5 | probability of obtaining a statistic less than or equal to min{W, 2 x E(W) - W}, adjusted for ties in such a manner that W is as large as possible |
| 6 | Wstatistic with average ranks used in case of ties |
| 7 | estimated standard error of Row 6 under the null hypothesis of no difference |
| 8 | standard normal score associated with Row 6 |
| 9 | two-sided p-value associated with Row 8 |
