Alex Herbert created STATISTICS-98:
--------------------------------------
Summary: 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
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.
