| Summary: | 0000504: FIXED: minor bug in the sign test (two sided alternative) | ||||
| Description: |
Sign test returns incorrect value for BothTails (slightly larger than 1.0) when sample has same number of values at both sides of supposed median value. This bug was reported by Julin Urbano: > double[] data = new double[] { 1, 2, 3, -4, -5, -6 }; > alglib.onesamplesigntest(data, data.Length, 0, out both, out left, out right); > and you'll see that the 2-tailed p-value (variable both) is 1.3125, > which can't happen :-) |
