Description

I'm very interested in using econml.dml.KernelDML to compute heterogeneous treatment effects. I am wondering if you could provide some suggestions on following:

  1. Should we try to tune dim and bw parameters in econml.dml.KernelDML? If so, what is the best way to tune them? With standard predictive analysis we can use cross-validations, but for causal analysis not sure if this is the best way.
  2. To use KernelDML, should we pre-process the features (e.g., normalize features in X matrix).

Thank you!

  3. Fork the repository and make your change on a branch.
  4. Open a pull request that references the issue number.

Research direction

Start with the econml.dml.KernelDML entry point and investigate the requested guidance on tuning dim and bw and preprocessing the X matrix. The issue names no files or tests and does not define a concrete documentation change; done would require an agreed methodological recommendation and a documented answer.
