void wilcoxonv(double p, int n, int *w0, int *w1);
Returns two critical points of the Wilcoxon Signed Rank Test null distribution function with sample size of n trials such that P(W ≤ w0) ≤ p ≤ P(W ≤ w1).
Parameters:
p | Cummulative probability. |
---|---|
n | Sample size |
w0 | Lower bound critical point. |
w1 | Upper bound critical point. |
Returns:
On exit, w0 and w1 are set such that P(W ≤ w0 | n) ≤ p ≤ P(W ≤ w1 | n)
Errors:
NUMERICS_ERROR
is raised if n ≤ 0, p ≤ 0, or p ≥ 1
Usage:
int w0, w1;
wilcoxonv(.5, 10, &w0, &w1)
