Class CorrelationStatsTest

java.lang.Object
ubic.gemma.core.util.math.CorrelationStatsTest
public class CorrelationStatsTest extends Object
Unit tests for CorrelationStats — the static stats facade used across coexpression, batch-confound detection, and PCA-correlate analyses. Covers the deterministic, lookup-free entry points: byte encoding/decoding, Fisher transform + inverse, validity check, and edge cases of p-value computation.
