Some functions here are no longer needed, since we now have newer versions of Jython (we were at v2.2 when I started this). But, I did manage to squeeze in a simple linear and polynomial regressions. > [@Math Extensions for Ignition](https://forum.inductiveautomation.com/t/math-extensions-for-ignition/3106): > > EDIT 2017-07-13: Things have changed enough that this first post is getting revamped. EDIT 2019-08-08: Re-uploaded due to broken link Some useful math functions just aren’t available through scripting. This is an attempt to rectify some of it.
