With R > 4.3.0, using && with non-scalar throws an error. In the logic section, answering the question dealing with && gives an error, using `skip()` will not advance and...

This PR modifies `get_X()` in `predict.lm_robust()` to appropriately create model matrices for new data predicted from `lm_lin()` models with multi-valued and factorial treatments, and fixes #415. Changes in this PR:...

Revisions to prediction with lm_lin()

1

Currently prediction does not work for `lm_lin()` with multi-valued or factorial treatments. This is because of how `predict.lm_robust()` handles generation of the lin estimator model matrix with new data. The...

This issue is about a method proposed in the tutorial, [Evaluating a causal forest fit](https://grf-labs.github.io/grf/articles/diagnostics.html). One heuristic method to detect heterogeneity described in the tutorial over-rejects under the null, I...
