A Multiscale Ball Test for Conditional Mean Independence
Simon Rudkin, Wanling Rudkin
Tests of conditional mean independence can lose power when departures are confined to a bounded part of a multivariate predictor space and the relevant spatial scale is unknown. We…
ballmapper: Applying Topological Data Analysis Ball Mapper in Stata
Simon Rudkin, Wanling Rudkin
Topological Data Analysis Ball Mapper (TDABM) offers a model-free visualization of multivariate data which does not necessitate the information loss associated with dimensionality…
An Introduction to Topological Data Analysis Ball Mapper in Python
Simon Rudkin
Visualization of data is an important step in the understanding of data and the evaluation of statistical models. Topological Data Analysis Ball Mapper (TDABM) after Dlotko (2019),…
An Introduction to Topological Data Analysis Ball Mapper in R
Simon Rudkin
The Topological Data Analysis Ball Mapper (TDABM) algorithm of Dlotko (2019) provides a model free means to visualize multi-dimensional data. The visualizations are abstract two-di…
