Valid Improved Sparsity A-Learning for Optimal Treatment
Decision
Description
Valid Improved Sparsity A-Learning (VISA) provides a new method for selecting important variables involved in optimal treatment regime from a multiply robust perspective. The VISA estimator achieves its success by borrowing the strengths of both model averaging (ARM, Yuhong Yang, 2001) and variable selection (PAL, Chengchun Shi, Ailin Fan, Rui Song and Wenbin Lu, 2018) . The package is an implementation of Zishu Zhan and Jingxiao Zhang. (2022+).
