Joel Bernstein updated SOLR-11160: ---------------------------------- Attachment: SOLR-11160.patch Added uniformDistribution and tests. > Add normalDistribution, sample and kolmogorovSmirnov Stream Evaluators > ---------------------------------------------------------------------- > > Key: SOLR-11160 > URL: https://issues.apache.org/jira/browse/SOLR-11160 > Project: Solr > Issue Type: New Feature > Security Level: Public(Default Security Level. Issues are Public) > Reporter: Joel Bernstein > Assignee: Joel Bernstein > Fix For: master (8.0), 7.1 > > Attachments: SOLR-11160.patch, SOLR-11160.patch > > > This ticket digs deeper into *probability distributions*, which are a key > foundation of statistics. > Three new functions are introduced: > 1) *normalDistribution*: This is a distribution function which returns a > normal distribution generator. It is designed to be used with both the > *sample* and the *kolmogorovSmirnov* functions. Eventually a function will be > added for every distribution supported by *Apache Commons Math*. > 2) *sample*: Returns array of numbers that conforms to a given distribution. > You pass it a distribution function and size and it returns the array that > conforms to the distribution. > 3) *kolmogorovSmirnov*: Performs a goodness of fit test for distributions. > This function can will do both a one and two side test. The one sided test > compares a sample to a distribution function. The two sided test compares two > samples to see if that were pulled from the same distribution. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
