[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:
