The trigger-failure parameter is higher for recorded delays in a gamma model of 126 ds000030 runs.
In a pooled gamma race model of 126 CONTROL scanner runs from OpenNeuro ds000030 snapshot 1.0.0, the fitted trigger-failure parameter was 0.325393 for recorded delays, 0.187804 for hybrid delays, and 0.190519 for planned delays. The model estimated gamma shape and mean together. Recorded-minus-hybrid and recorded-minus-planned differences were 13.758891 and 13.487356 percentage points. Likelihood profile support ranges, conditional on fixed GO estimates and independent trials, were [0.303352, 0.347845], [0.164716, 0.211576], and [0.167607, 0.214125]. These are sample and model results, not population confidence intervals or biological failure rates. All fits had large descriptive errors at short delays; actual tone onset is unknown, and the recorded delay can depend on the response in the same trial. Shared STOP parameters, fixed GO estimates, adaptive delays, response deadlines, and only 32 STOP trials per run limit interpretation. The fitted difference does not identify which delay field represents actual tone onset.
