Manual implementation of the Hopkins statistic. Values > 0.5 suggest
non-random clustering structure; values near 0.5 indicate uniform
distribution.
Usage
.nm_hopkins(mat, n_sample = 10L, seed = 42L)
Arguments
- mat
Numeric matrix (proteins x samples), no NAs.
- n_sample
Integer. Number of points to sample (default 10, capped at
ncol - 1).
- seed
Integer. Seed used for the random reference points, so the
statistic is reproducible across calls. The caller's RNG state is restored
on exit.
Value
Numeric scalar (0-1).
