Things to do to improve the documentation:
- examples and tutorials
- something that shows how to run the MCMC directly, without the BART interface
- something that shows how to deal with predictors
- how to choose the cutpoint grid
- dummies
- collinearity
- split the internal reference in multiple pages
- right now there are a few html pages with many functions listed in each, this is hard to navigate
- alternatively, long pages would be fine if there was an index or a sidebar
- use a more modern html template
- write a math reference
- There is no complete reference for the math in the BART MCMC. There are some scattered pieces here and there. Recently I fixed a problem (b3d8a2f) in the MCMC that originated in a formula I copied from the appendix of the bartMachine paper (Kapelner & Bleich 2016, JSS), which was subtly wrong. So a precise reference may be quite useful to the BART community.
