randomization_test_R

Base R randomization test: difference in means + optional fiducial interval

Provides hardware-accelerated tools for performing rerandomization
and randomization testing in experimental research. Using a 'JAX' backend, the
package enables exact rerandomization inference even for large experiments
with hundreds of billions of possible randomizations. Key functionalities
include generating pools of acceptable rerandomizations based on covariate
balance, conducting exact randomization tests, and performing pre-analysis
evaluations to determine optimal rerandomization acceptance thresholds. The
package supports various hardware acceleration frameworks including 'CPU',
'CUDA', and 'METAL', making it versatile across accelerated computing environments. This
allows researchers to efficiently implement stringent rerandomization designs and
conduct valid inference even with large sample sizes. The package is partly based on Jerzak and Goldstein (2023) <doi:10.48550/arXiv.2310.00861>.
