Negative-control test for an allegedly informative process channel

Description

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
)

Arguments

data	Input data.
process_columns	Columns to permute.
evaluator	Function returning one scalar out-of-sample score.
within	Optional grouping columns within which permutation occurs.
permutations	Number of negative-control permutations.
higher_is_better	Score direction.
seed	Random-number seed.

Value

An object of class "eye_process_negative_control", stored as a named list, with components "observed", "null", "p_value", "permutations", "process_columns", "within", "higher_is_better", "seed". It contains negative-control test for an allegedly informative process channel and associated metadata or diagnostics needed to interpret the result.
