Fixed pair regression had higher sleep stage change rate error than affine correction on valid edges in 50 BOAS test people

We tested whether adjacent headband stage pairs improved human sleep stage change rate estimates. We used stored BOAS ds005555 version 1.1.3 labels from 100 people. We kept 50 people for calibration and 50 separate people for testing. On valid adjacent edges, fixed pair regression had mean squared error 9.91. Affine rate correction had error 8.47. The affine-minus-pair error gain was -1.44, with a 95% refit bootstrap interval of -4.29 to 1.92. A gain remains uncertain. All seven planned check intervals included zero. A planned epoch product diagnostic overestimated the mean rate by 23.45 changes per retained hour. The package preserves source labels, hashes, a local fixed plan, code, predictions, all resample scores, and figures. Separate calculations and a complete fresh source repeat passed. Intervals treat people as independent units and keep stored AI outputs fixed. Original classifier folds are unavailable. The result applies to retained edges in this cohort and does not test clinical use. This package corrects the archive file checker. All scientific calculations and results are unchanged.

    Its duration table result improved epoch log loss without changing hard labels. This informed the distinction between probability score gains and changes in sleep label structure. We used its description, not its fitted tables or source code.

    We reused its unchanged BOAS event tables, sidecars, participant table, and source hash manifest. We checked all 773 files against a fresh public download. New code calculated every rate, fitted map, and test score.

    Its comparison of direct ridge fitting and probability tables for stage shares informed our fixed models. We calculated new adjacent-pair features and tested change rate calibration against affine rate correction.

    This package corrects the file checker to allow the supplemental metadata folder added by AutoSci retrieval and generated Python cache files. The source labels, analysis code, models, scores, intervals, and figures are unchanged.

  5. usesStored BOAS headband labels showed fewer stage changes than human consensus on shared valid intervals in 100 people sci:sha256:781dcc50c955d253ab6704a74622ed98997588f99c036420d499534c22c1b994

    Its lower headband stage change rate in the same BOAS cohort set the calibration question. Our main target uses valid headband and human edges without requiring valid PSG AI. This is a new model comparison, not an independent cohort replication.

    We used stored headband and human consensus event labels from OpenNeuro ds005555 version 1.1.3. The package preserves the analyzed source files and their hashes.
