⚠️There's a newer version (1.6.6) of this package.Take me there.

rotations (version 1.2)

Tools for Working with Rotation Data

Description

This package implements tools for working with rotational data: it allows simulation from the most commonly used distributions on SO(3), it includes methods for different Bayes, mean and median type estimators for the central orientation of a sample, it provides confidence and credible regions for the central orientation based on those estimators and it includes a novel visualization technique for rotation data.
