| Row | Statistics |
|---|---|
| 0 | gamma |
| 1 | Kendall's |
| 2 | Stuart's |
| 3 | Somers' D for rows (given columns) |
| 4 | Somers' D for columns (given rows) |
| 5 | product moment correlation |
| 6 | Spearman rank correlation |
| 7 | Goodman and Kruskal |
| 8 | Goodman and Kruskal |
| 9 | uncertainty coefficient U (symmetric) |
| 10 | uncertainty |
| 11 | uncertainty |
| 12 | optimal prediction |
| 13 | optimal prediction |

| 17 | Test for linear trend in row probabilities if table.GetLength(0) = 2. Test for linear trend in column probabilities if table.GetLength(1) = 2 and table.GetLength(0) is not 2 |
| 18 | Kruskal-Wallis test for no row effect |
| 19 | Kruskal-Wallis test for no column effect |
| 20 | kappa (square tables only) |
| 21 | McNemar test of symmetry (square tables only) |
| 22 | McNemar one degree of freedom test of symmetry (square tables only) |
The columns are as follows:
| Column | Value |
|---|---|
| 0 | estimated statistic |
| 1 | standard error for any parameter value |
| 2 | standard error under the null hypothesis |
| 3 | t value for testing the null hypothesis |
| 4 | p-value of the test in column 3 |
If a statistic cannot be computed, or if some value is not relevant for the computed statistic, the entry is NaN (Not a Number).
In the McNemar tests, column 0 contains the statistic, column 1 contains the chi-squared degrees of freedom, column 3 contains the exact p-value (1 degree of freedom only), and column 4 contains the chi-squared asymptotic p-value. The Kruskal-Wallis test is the same except no exact p-value is computed.
