Abstract: Highlights•A control chart-based symbolized conditional transfer entropy method is proposed.•The proposed SCTE method is used for root cause analysis of process disturbance.•The diagnosis performance is evaluated by three indices.•The feasibility of the model is illustrated with the Tennessee Eastman process.
