Tablemath

1 Preface

Math and stats modelling with table ergonomics

What is this about?

This project is an initial attempt to create a Clojure library for math and statistics which is friendly to tech.ml.dataset and Tablecloth datasets and uses the functionality of Fastmath. It is also intended to compose well with Tableplot layered plotting. It is highly inspired by R and its packages.

In a way, it is intended to be a user-friendly compatiblity layer across these libraries.

Possibly, after the details clarify, it will be merged into one of the other Scicloj libraries.
