[jira] [Created] (MATH-693) StatUtils, DescriptiveStatistics and
SummaryStatistics should expose population variance
StatUtils, DescriptiveStatistics and SummaryStatistics should expose population variance
----------------------------------------------------------------------------------------
Key: MATH-693
URL: https://issues.apache.org/jira/browse/MATH-693
Project: Commons Math
Issue Type: Improvement
Affects Versions: 2.2, 2.1, 2.0, 1.2, 1.1, 1.0
Reporter: Phil Steitz
Fix For: 3.0
Javadoc should be clearer that what is returned in the bias-corrected variance (rather than just linking to the Variance javadoc). StatUtils should add variance methods that take a boolean bias correction parameter and DescriptiveStatistics and SummaryStatistics should either expose a setter or similarly add methods with boolean arguments. We need to remember to fix the synchronized versions as well. Patches welcome!
