Mathijs Vogelzang created MATH-1421: ---------------------------------------
Summary: WilsonConfidenceInterval returning negative values Key: MATH-1421 URL: https://issues.apache.org/jira/browse/MATH-1421 Project: Commons Math Issue Type: Bug Affects Versions: 3.6.1 Reporter: Mathijs Vogelzang Wilson confidence intervals sometimes return negative values as the lower bound, e.g. IntervalUtils.getWilsonScoreInterval(19436, 0, 0.95).getLowerBound() returns -1.3549849074815073E-20 This is causing assertion fails in our code, which we have fixed it now by wrapping the confidence score bounds in Math.max(0, Math.min(1, bound)) until the method doesn't return wrong results anymore. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
