formulaML reference docs

This site is the reference manual for the ML.* custom functions in the formulaML Excel add-in. Every function you can call from a cell — ML.CLASSIFICATION.LOGISTIC, ML.FIT, ML.PREDICT, ML.PIPELINE, and the rest — has its own page here listing its arguments, its return type, and at least one working Excel example.

Where to start

  • New to formulaML? Read Getting started to install the add-in and train your first model.
  • Curious how a cell can hold a Python object? See the Object handles concept page.
  • Building your first model? Read The FIT/PREDICT pattern — every classifier, regressor, and clusterer follows the same three-step workflow.
  • Looking up a specific function? Jump straight to the Reference — namespaces are listed alphabetically.
