Did a kernR result decline to stand behind its own verdict?

TRUE when a reliability gate failed (the ESS floor, the proxymix density-ratio fit-quality gate, or the mechanism-consistency posterior-adequacy guard) and the result was stamped with the typed kernR_abstention marker. This is kernR's local mirror of the federation's is_orchestra_decline() predicate (ORCHESTRA_dev/integration/refusal_contract.R), scoped to the member's own result classes so calling code inside kernR does not need to depend on the composition-layer contract file.

Usage

is_kernR_abstention(x)

Arguments

x

Any object.

Value

A length-1 logical.

Examples

set.seed(42L)
n <- 60L
z <- matrix(rnorm(n * 2L), n, 2L)
x <- z[, 1L] + rnorm(n, sd = 0.5)
y <- 0.5 * x + rnorm(n, sd = 0.5)
res <- suppressWarnings(bd_hsic_test(x, y, z, min_ess_fraction = 0.999))
is_kernR_abstention(res)  # TRUE -- the ESS floor tripped
#> [1] TRUE
