LassoPath: LASSO path for the penalized logistic regression

Description

Fit an interaction uplift model via penalized maximum likelihood. The regularization path is computed for the lasso penalty at a grid of values for the regularization constant.

Usage

LassoPath(data, formula)

Arguments

data

a data frame containing the treatment, the outcome and the predictors.

formula

an object of class "formula" (or one that can be coerced to that class): a symbolic description of the model to be fitted.

Value

a dataframe containing the coefficients values and the number of nonzeros coefficients for different values of lambda.
