In VIM: Visualization and Imputation of Missing Values

Build a GAM formula with automatic smooth terms

Description

Constructs a formula for mgcv::gam() by wrapping numeric predictors with sufficient unique values in s() terms and keeping factors as linear terms.

Usage

build_gam_formula(target, features, data, min_unique = 4L, default_k = 10L)

Arguments

target	Character: target variable name
features	Character vector: predictor variable names
data	Data frame used to check variable types and unique value counts
min_unique	Integer: minimum number of unique values for a numeric predictor to be wrapped in s(). Default 4 (mgcv needs at least k=3 knots).

Value

A formula object suitable for mgcv::gam()
