onlineChange 0.0.5

Quickest change detection algorithms for online streaming data in python.

The 'onlineChange' python package

The onlineChange python package is designed to quickest detect any change in distributions for online streaming data, supporting any user-specified distributions. It supports sequential Monte Carlo to perform Bayesian change point analysis, where the parameters before or after the change can be unknown. It also supports likelihood ratio based test to determine the stopping time (i.e. when change occurs).

This is still an ongoing project by a group of researchers from the University of Minnesota. The published software here is an initial version that is ready to use.
