Negative-control test for an allegedly informative process channel

The user supplies a complete evaluation callback. eyeprocess permutes the named process columns, optionally within grouping strata, and compares the observed score with the permutation distribution.

Usage

negative_control_process_test(
  data,
  process_columns,
  evaluator,
  within = NULL,
  permutations = 100L,
  higher_is_better = TRUE,
  seed = 20260808L
)

evaluator

Function returning one scalar out-of-sample score.

within

Optional grouping columns within which permutation occurs.
