%description
Fast tools for unequal probability sampling in multi-dimensional spaces,
implemented in Rust for high performance. The package offers a wide range
of methods, including Sampford (Sampford, 1967,
<doi:10.1093/biomet/54.3-4.499>) and correlated Poisson sampling
(Bondesson and Thorburn, 2008, <doi:10.1111/j.1467-9469.2008.00596.x>),
pivotal sampling (Deville and Tillé, 1998, <doi:10.1093/biomet/91.4.893>),
and balanced sampling such as the cube method (Deville and Tillé, 2004,
<doi:10.1093/biomet/91.4.893>) to ensure auxiliary totals are respected.
Spatially balanced approaches, including the local pivotal method
(Grafström et al., 2012, <doi:10.1111/j.1541-0420.2011.01699.x>),
spatially correlated Poisson sampling (Grafström, 2012,
<doi:10.1016/j.jspi.2011.07.003>), and locally correlated Poisson sampling
(Prentius, 2024, <doi:10.1002/env.2832>), provide efficient designs when
the target variable is linked to auxiliary information.
