Function reference • tidyfit

Basic functionality

The functions regress() and classify() provide basic modeling wrappers for tidy data.

regress: Linear regression on tidy data

classify: Classification on tidy data

Generic methods

The ‘tidyfit.models’ frame produced by ‘regress()’ or ‘classify()’ can be used to obtain coefficients or predictions.

coef(<tidyfit.models>): Extract coefficients from a tidyfit.models frame

predict(<tidyfit.models>): Predict using a tidyfit.models frame

fitted(<tidyfit.models>): Obtain fitted values from models in a tidyfit.models frame

residuals(<tidyfit.models>): Obtain residuals from models in a tidyfit.models frame

Modeling engine

The model wrapper m() standardizes a large number of linear regression and classification algorithms.
