Draws without replacement at a smaller sample size; valid under
weaker conditions than the bootstrap. No clean CRAN function
exposes the same (data, statistic, subsample_size, n_subsamples)
API; np's npsubsample is closest but is kernel-specific.
Kept as an in-house implementation and flagged
novel/no-clean-CRAN-equivalent.
Usage
subsampling(
data,
statistic,
subsample_size = NULL,
n_subsamples = 1000L,
ci_level = 0.95,
seed = 42L
)
