Specify a confirmation error model

Usage

confirmation_plan(
  error = c("independent", "block_robust", "sign_flip"),
  n_resamples = 999L,
  seed = 1L
)

Arguments

error

Independent Gaussian rows, a CR1 sandwich over independent blocks, or a restricted-residual block wild bootstrap with Rademacher signs.

n_resamples

Number of Monte Carlo sign draws (at least 99).

seed

Nonnegative integer seed. Resampling restores the caller's RNG.

Value

A pattern_confirmation_plan.

Details

The independent model uses residual degrees of freedom. Block sandwich t and Wald F tests use number of blocks minus one and are small-sample approximations. The sign-flip option uses the same sandwich statistics and refits residuals under each null. With estimated nuisance effects this is an approximate wild bootstrap, not an exact permutation test. Independent blocks and enough blocks for the tested dimension are required. No option establishes independence from row labels alone.
