Methods for online / incremental estimation of distributional regression models

ROLCH: Regularized Online Learning for Conditional Heteroskedasticity

Introduction

This package provides online estimation of models for distributional regression respectively models for conditional heteroskedastic data. The main contribution is an online/incremental implementation of the generalized additive models for location, shape and scale (GAMLSS, see Rigby & Stasinopoulos, 2005) developed in Hirsch, Berrisch & Ziel, 2024.

Please have a look at the documentation or the example notebook.

We're actively working on the package and welcome contributions from the community. Have a look at the Release Notes and the Issue Tracker.
