A simulated dataset containing variables for within-subject mediation analysis.
The dataset includes four within-subject variables (A, B, C, D), each measured at three levels:
A1, A2, A3: Levels of within-subject variable A (e.g., mediator conditions).
B1, B2, B3: Levels of within-subject variable B (e.g., outcome conditions).
C1, C2, C3: Levels of within-subject variable.
D1, D2, D3: Levels of within-subject variable.
