> SignificanceResult interface does not reject invalid p-values
> -------------------------------------------------------------
>
> Key: STATISTICS-98
> URL: https://issues.apache.org/jira/browse/STATISTICS-98
> Project: Commons Statistics
> Issue Type: Bug
> Components: inference
> Affects Versions: 1.3
> Reporter: Alex Herbert
> Assignee: Alex Herbert
> Priority: Trivial
> Fix For: 1.4
>
>
> The SignificanceResult interface has a default method:
> {code:java}
> default boolean reject(double alpha) {
> Arguments.checkSignificance(alpha);
> return getPValue() < alpha;
> } {code}
> The p-value may be outside of the range [0, 1], or NaN. This will invalidate
> the rejection of a result.
> In cases where a test computes a NaN p-value then the result will be silently
> accepted when testing using a critical alpha (i.e. not rejected).
> Issue identified using a security scan.
