Abstract

This article presents validation tests to check a predictive model over time. These validation tests are like individuals, X̄ and S control charts. The individuals validation test is used when there are no replicates at the checked time points. The X̄ and S validation tests can be used when there are replicates. Their power is evaluated under various scenarios via a simulation study. Based on these results, the X̄ and S validation tests are recommended when there are replicate measurements.
