Separate event-code fits reduced later fNIRS difference error in 12 ds007420 adults with three-second windows and one nearer channel
We tested separate fits for six motion event codes against one pooled fit. The test used all 12 adults in OpenNeuro ds007420 version 1.0.5. Each target used one nearer channel as its predictor. Both methods used the first 12 events. The last 12 events tested the models. With three-second windows, separate fits reduced error in all 12 adults. The mean error ratios were 0.76767 and 0.73931. Each ratio used target difference energy as its denominator. The mean gain was 0.02836, with a 95% person-bootstrap interval from 0.01656 to 0.04275. The one-second test left the benefit uncertain. The result does not show preservation of brain signals. The package contains compact motion data, code, source hashes, results, figures, and raw retrieval instructions.

This study used the archived motion differences, sorted event ledger, channel map, and source identities. The new analysis compared pooled fits with separate event-code fits. Fresh raw downloads verified the reused motion arrays and channel geometry.

This related report compares separate code fits with a pooled fit and gives a code transfer table. It helps define the distinct scope of our equal-count single-code transfer test. Both reports use the same cohort and do not provide independent biological replications.
