Misc Statistics and Machine Learning codes in R

This package provide matlab code to realized 3 popular machine learning method for Dynamic Treatment Regime. A intermediate version of the paper is https://arxiv.org/abs/1611.02314. The paper started in 2012, and is currently in press at Stat in Medicine. We also provide R code for functions in the package in 'DTRlearn'. The matlab code performs more stable than R.
