%description
Performs hypergraph-based setwise variable selection with false discovery
rate control (Organ, Kenney & Gu, 2026, <doi:10.48550/arXiv.2606.20514>).
The idea is, in addition to selecting individual predictors when there is
sufficient evidence, to also test all pairs of predictors, and when there
is insufficient evidence to be sure which is the true predictor, it will
select possibly overlapping pairs, for which there is strong evidence that
at least one is a true predictor. The method is designed to control a
generalised false discovery rate, where discoveries are counted based on
the number of independent sets. The function of this package is similar to
the 'hypergraph.sizing' package, but this package is optimised for faster
computation in the case where we test all pairs of predictors. The package
also includes functions for counting independent sets in a graph or
hypergraph, either exactly or approximately. There is also a very limited
function for isotonic regression, which is designed for fast computation
in the specific case needed for hypergraph variable selection, rather than
for general use.
