llm: Create Logit Leaf Model

In arnodc2/LLM: Logit Leaf Model

Description

This function creates the logit leaf model. It assumes a dataframe with numeric values as input and a corresponding vector with dependent values. Decision tree parameters threshold for pruning and number of observations per leaf can be set.

Usage

llm(df, y_value, threshold_pruning, nbr_obs_leaf)

Arguments

df	dataframe containing numerical independent variables
y_value	numerical vector of dependent variable. Currently only two class classification is supported
threshold_pruning	threshold for impurity
nbr_obs_leaf	the minimum number of observations in a leaf node

Value

a LLM object containing decision rules that define segments and logistic regressions per segment
