Single-level and multi-level mediation analyses for any kind of data, with bootstrap-based significance testing. Neuroimaging-oriented functions allow for mediation effect parametric mapping (mapping of mediation effects across the brain) and multivariate mediation.
I have got the mediation toolbox at GitHub: https://github.com/canlab/MediationToolbox. I followed every steps as described in the “Mediation sample data walkthrough”. However, a program error interrupt occurred in the Step 7: Run the mediation and only one bootstrapped histograms was shown (Please see the attachment). Could you please do me the favor instructing me to overcome this program error? #3
