Provides functions for assigning treatments in randomized experiments using near-optimal threshold blocking. The package is made with large data sets in mind and derives blocks more than an order of magnitude quicker than other methods.
See quickblock for the main blocking function.
See the package's website for more information: https://github.com/fsavje/quickblock.
Bug reports and suggestions are greatly appreciated. They are best reported here: https://github.com/fsavje/quickblock/issues.
