[jira] [Updated] (SOLR-12631) Improvements to the harmonicFit Stream Evaluator

     [ https://issues.apache.org/jira/browse/SOLR-12631?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Joel Bernstein updated SOLR-12631:
----------------------------------
    Description: 
The current version of the *harmonicFit* Stream Evaluator is very hard to use. This ticket adds two important capabilities to the function:

1) Makes an initial guess internally so the fit to a sine wave is much better.

2) Returns a function that can used by the predict function.
