Description

Abstract: This study focused on variable selection using lasso regression to predict future health care costs in claims data. It demonstrated that reducing the number of input features into a linear regression model through variable selection could preserve most of the prediction power. In addition, lasso regression performed only slightly better than linear regression in predicting future costs.

Learning Objective 1: The primary goal of the study is to gain insights into how variable selection from the past history of health care encounters may impact prediction of future health care costs.
