[jira] [Created] (MATH-1379) LoessInterpolator can update bandwidth interval incorrectly

Richard Wilkinson created MATH-1379:
---------------------------------------

             Summary: LoessInterpolator can update bandwidth interval incorrectly
                 Key: MATH-1379
                 URL: https://issues.apache.org/jira/browse/MATH-1379
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 3.6.1
            Reporter: Richard Wilkinson


LoessInterpolator.updateBandwidthInterval assumes that the bandwidth interval cannot step by more than one index value for each call. This may not be true if the xvals are unevenly spaced (or are so after points with zero weight are omitted).

Patch available with additional tests.
