Tandem clustering with invariant coordinate selection
About tandem clustering with ICS
Tandem clustering is a well-known technique aiming to improve cluster identification through initial dimension reduction. However, the usual approach using principal component analysis (PCA) has been criticized for focusing solely on inertia so that the first components do not necessarily retain the structure of interest for clustering. To address this limitation, we propose a new tandem clustering approach based on invariant coordinate selection (ICS).
More information can be found in our article:
A. Alfons, A. Archimbaud, K. Nordhausen and A. Ruiz-Gazen (2024). Tandem clustering with invariant coordinate selection. Econometrics and Statistics. doi: 10.1016/j.ecosta.2024.03.002.
Reproduce results
This repository provides a collection of R scripts to reproduce all examples, simulations, and figures in our article.
The easiest way to reproduce the results is to clone this repository with
RStudio. Running the
scripts within the resulting RStudio project ensures that there are no issues
with file paths for storing or reading results, or for producing files
containing plots. In addition, the RStudio project uses
renv to make sure that the correct
versions of all required R packages are used. After opening the RStudio
project for the fist time, please type renv::restore() on the R command
line to retrieve the correct versions of all required packages.
Please note that this repository is rather large because it also contains R data files with all simulation results. This way, if you only want to quickly reproduce the figures with simulation results, you do not actually need to run the simulations first.
