Hello,

I was wondering what is the algorithm used in Timelion for the .holt() function. Based on the name I would say Holt-Winters ?

Is there any way to customise the algorithm ? (More than the 4-5 parameters ?)  
Can we also implement our own algorithms in Timelion ?

Basically it is to do better forecasting, but i don't think it is the best way to do it in Kibana/Timelion

Thanks

Correct, it's [Moving Average Aggregation | Elasticsearch Reference [5.4] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/5.4/search-aggregations-pipeline-movavg-aggregation.html#_holt_winters)

Yes, see [GitHub - Fermium/mathlion: Mathlion is an advanced math plugin for Kibana's Timelion](https://github.com/fermiumlabs/mathlion)

Wouah, thanks a lot !

This MathLion seems to be exactly what I was looking for.
