Application

Causal inference algorithms:

1. The Two Model Approach

  • Separate models for treatment and control groups are trained and combined to derive average treatment effects.

2. Interaction Term Approach - Lo 2002

  • An interaction term between treatment and covariates is added to the data to allow for a basic single model application.

3. Response Transformation Approach - Lai 2006; Kane, Lo and Zheng 2014

  • Units are categorized into four classes to derive the treatment effected from positive class attributes.

4. Generalized Random Forest - Athey, Tibshirani, and Wager 2019

  • An application of an honest causalaity based splitting random forest.

Evaluation metrics:

1. Qini and AUUC Scores

  • Comparisons across stratefied, ordered treatment response groups are used to derive model efficiency

2. GRF Confidence Intervals

  • Confidence intervals are created using GRF's standard deviation across trials
