Apache Commons Statistics: Inference
Apache Commons Statistics provides statistical hypothesis testing.
Example:
import org.apache.commons.statistics.inference.ChiSquaredTest;
double[] expected = ...
long[] observed = ...
double alpha = 1e-3;
// Fail if we can *reject* the null hypothesis with confidence (1 - alpha)
// that the observed match the expected
if (ChiSquareTest.withDefaults().test(expected, observed).reject(alpha)) {
// Significant deviation from the expected ...
}
