chainladder.PatsyFormula

class chainladder.PatsyFormula(formula=None)

A sklearn-style Transformer for patsy formulas.

PatsyFormula allows for R-style formula preprocessing of the design_matrix of a machine learning algorithm. It’s particularly useful with the DevelopmentML and TweedieGLM estimators.

Parameters:

formula: str

A string representation of the regression model X features.

Attributes:

design_info_:

The patsy instructions for generating the design_matrix, X.

Methods

fit_transform(X[, y])	Fit to data, then transform it.
get_metadata_routing()	Get metadata routing of this object.
get_params([deep])	Get parameters for this estimator.
set_fit_request(*[, sample_weight])	Request metadata passed to the fit method.
set_output(*[, transform])	Set output container.
set_params(**params)	Set the parameters of this estimator.
