Box-A2 has no data past ~day 13, so the full-range days x tDCS interaction extrapolates A2's slope and is confounded (spuriously significant, wrong sign). Add the _d0_13 window (equal anchor coverage) and a report warning when the two groups' day coverage is unequal. In the fair 0-13 window the interaction is n.s. with a POSITIVE slope diff and the Day-1 tDCS effect is n.s. -- matching the paper's 'equal on Day 1' direction (underpowered at n=8). Suite 32/32.

function tdcs_glm(scenario)
|
|
%TDCS_GLM Run one tDCS GLM scenario end-to-end and report it.
|
|
% TDCS_GLM(SCENARIO) runs the full pipeline for one named scenario --
|
|
% TDCS_SCENARIO_DATA -> TDCS_MODELS -> TDCS_REPORT -- printing the
|
|
% report to the console and writing it to
|
|
% analysis/matlab/results/<SCENARIO>.txt.
|
|
%
|
|
% SCENARIO must be one of (case-sensitive):
|
|
% unmerged_full, unmerged_d0_10,
|
|
% mergeA2_full, mergeA2_d0_10,
|
|
% mergeB2_full, mergeB2_d0_10
|
|
% or a linear "days x tDCS" mixed model (Box-B2 vs Box-A2, per the paper):
|
|
% lme_unmerged_full, lme_unmerged_d0_10, lme_unmerged_d0_13,
|
|
% lme_mergeA2_full, lme_mergeA2_d0_10, lme_mergeA2_d0_13,
|
|
% lme_mergeB2_full, lme_mergeB2_d0_10, lme_mergeB2_d0_13
|
|
% The _d0_13 window ends where Box-A2 runs out of data, giving both anchor
|
|
% groups equal day coverage (the fair window for the interaction).
|
|
%
|
|
% Each case below is a self-contained, independently invocable call of
|
|
% the same three-function pipeline; they are enumerated explicitly
|
|
% (rather than sharing one generic branch) so each scenario name is
|
|
% greppable on its own, per the project's spec.
|
|
%
|
|
% Example:
|
|
% tdcs_glm('mergeB2_full')
|
|
%
|
|
% See analysis/tdcs_glm.py (the Python this ports) and
|
|
% docs/superpowers/plans/2026-07-20-matlab-tdcs-analysis.md (Task 4).
