[jira] [Updated] (SOLR-8964) Add CorrelateStream to compute Pearson's correlation coefficient for two streams

     [ https://issues.apache.org/jira/browse/SOLR-8964?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Joel Bernstein updated SOLR-8964:
---------------------------------
    Description: 
The CorrelateStream will compute the Pearsons correlation coefficient for two streams. 

Sample syntax below will calculate the Pearsons correlation for two time series streams. See SOLR-8963 for the *time* function:

{code}
correlate(rollup(time(search()),
          rollup(time(search()))
{code}

  was:

{code}
correlate(rollup(time(search()),
               rollup(time(search()))
