[jira] [Updated] (SOLR-10696) Add empirical distribution and
percentile Stream Evaluators
[ https://issues.apache.org/jira/browse/SOLR-10696?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joel Bernstein updated SOLR-10696:
----------------------------------
Description:
The *empirical distribution* Stream Evaluator loads an array and creates a distribution based only on the underlying data. It returns summary stats for the distribution.
The *percentile* Stream Evaluator returns the percentile of a number for a specific empirical distribution.
Syntax:
{code}
e = empiricalDistribution(colA)
p = percentile(e, 23)
{code}
Implementation provided by Apache Commons Math
