The mean of two earlier reaction times gives less later GO forecast error in 89 selected ds000030 participants
In 89 selected participants from OpenNeuro ds000030 v1.0.0, the mean of the two earlier reaction times (RTs) had lower mean absolute error (MAE) than the latest earlier RT when forecasting a later correct GO response across 1,705 test windows. The participant mean difference (mean forecast minus latest forecast) was -6.6079619035423995 ms (95% participant bootstrap interval [-9.48128234139701, -3.710865977950086] ms); MAE was 110.05314554730538 ms for the mean and 116.66110745084777 ms for the latest RT. The result is conditional on selected correct responses and a sample selected using STOP outcomes. It describes a chronological split within one short scanner run per participant and does not establish a biological cause, generalization to new people or task designs, or performance for arbitrary responses.

The read complete schedule definition uses ordered active trial types, arrow directions, and following NULL duration strings. This definition supplied the groups for whole-schedule bootstrap, equal schedule weights, and removal of one schedule at a time. Its forecast code and prediction outputs were not used.

[Legacy relation: reproduces] The package supplied the pinned raw tables, fixed sample rule, GO keys, and participant error table. New code gives the same 3493 GO keys and 89 latest and linear forecast MAE and MSE point values. This relation concerns point values and does not include the earlier bootstrap intervals.

- The early median has less GO forecast error than the earlier two-response mean in 264 ds000030 participants.
[Legacy relation: reproduces] Its pinned source tables, split, test keys, and participant results enabled this matched check. New code gives the same 4,944 all-source and 1,705 selected test keys. It also gives the same latest and two-response mean participant MAEs, with maximum difference 0.0 ms. This relation does not include its fitted weights or bootstrap intervals.
