If you want precise traditional stats just do that. </P> Wed, 15 Aug 2018 14:34:29 GMT starcher 2018-08-15T14:34:29Z https://community.splunk.com/t5/Splunk-Enterprise-Security/What-is-the-best-method-of-calculating-variance-Extreme-Search/m-p/395308#M4339 <P>I currently have several behavioral anomaly searches that report users exhibiting authentication behavior that is X number of standard deviations above their mean or just in the 9Xth percentile based on a baseline period of behavior. After reading George Starcher's blog entries on the subject of Extreme Search I am considering implementing those searches using that app, but I am concerned that I am losing precision because I can't say for certain that "anomalous" means three standard deviations above the mean. I would like to hear about other users' experiences doing the same and whether you think the migration is worth the effort.</P> Wed, 08 Aug 2018 17:43:50 GMT https://community.splunk.com/t5/Splunk-Enterprise-Security/What-is-the-best-method-of-calculating-variance-Extreme-Search/m-p/395308#M4339 joeldavideng 2018-08-08T17:43:50Z https://community.splunk.com/t5/Splunk-Enterprise-Security/What-is-the-best-method-of-calculating-variance-Extreme-Search/m-p/395309#M4340 <P>Extreme search is "fuzzy".
