%TMODELS Tests for tdcs_models (Task 3: GLMM + per-animal + classify).
|
|
%
|
|
% Authored per TDD: written before tdcs_models.m existed, so it is
|
|
% expected to fail until the model-fitting function is implemented.
|
|
% MATLAB R2025b + Statistics and Machine Learning Toolbox IS licensed
|
|
% in this environment (unlike Tasks 1-2), so this suite is actually
|
|
% run: RED before tdcs_models.m existed, GREEN after.
|
|
%
|
|
% Per-animal golden values (Box-B2 vs Box-A2, pure stats: per-subject
|
|
% mean success for "count", per-subject pooled sum(success)/sum(total)
|
|
% for "rate"; Welch two-sided TTEST2, one-sided 'right' RANKSUM) were
|
|
% independently reproduced with a throwaway Python script against
|
|
% analysis/tdcs_reach_data.csv (equal_var=False t-test,
|
|
% mannwhitneyu(..., alternative='greater')), confirming the plan's
|
|
% Task 3 golden-value table to better than 1e-3 in every cell (see
|
|
% task-3-report.md). They must match to 3 decimals (AbsTol 0.005) --
|
|
% do not loosen this tolerance.
|
|
%
|
|
% GLME-derived checks (H2 odds/incidence-rate ratios, classification)
|
|
% are checked loosely (direction/magnitude), since GLMM (subject
|
|
% random intercept) is not numerically identical to the Python's GEE
|
|
% (population-average, robust SEs) -- see the plan's Global
|
|
% Constraints and analysis/METHODS.md.
