Rank-based regression in Excel
This tutorial shows how to run a rank-based regression in Excel using the XLSTAT-R engine.
What is rank-based regression?
Rank-based regression allows estimating rank-based coefficients for linear models. Those estimations are considered to be more robust with regards to outliers compared to more classical estimation approaches.
The Rank-based regression function developed in XLSTAT-R calls the rfit function from the Rfit package in R (John Kloke).
