A screening algorithm in simulation of mediation models

Several literatures mentioned that outlier identification is a part of the data screening process which should be done routinely before statistical analyses. Specifically in mediation analysis, the clean data generating process in a simulation is needed before continuing to further analysis so that allows accurate result of an analysis can be obtained. We proposed a screening algorithm in mediation analysis, named Clean-Assured Data Generating Procedures (CADGP). The screening method uses ModDRGP, a newly outlier detection method which provided a procedure for obtaining clean datasets. The generated dataset through CADGP will be free of high leverage points. The CADGP is needed especially in simple mediation analysis which is usually used in social sciences.
