Does the bootstrap test of “no hard messages” stay valid when the auditors differ in accuracy?

research/ambient-hlrtmis

Does the no-hard-messages bootstrap test keep its level when the three auditors differ in accuracy: 100 h = 0 draws per cell give rejection 0.00-0.10 at nominal 0.05, no inflation seen (stylised).

5 tests

What it found

Data with no hard messages but three auditors of unequal accuracy (equal, 0.9/0.8/0.7, 0.95/0.8/0.65; mean 0.8), tested against a null that forces one shared auditor matrix. With 100 draws per cell at n = 200 and 500, rejection at nominal 5% is 6–10/100 at 200 and 0–6/100 at 500; five of six exact intervals contain 0.05 and the sixth (0/100) is conservative. No inflation is seen, but intervals are about ±0.05 wide. Stylised: accuracy heterogeneity only, level only.
