...David A. Swanson; Jeff Tayman; Charles F. Barr Abstract Mean absolute percentage error (MAPE), the measure most often used for evaluating subnational demographic estimates, is not always valid. We describe guidelines for determining when MAPE is valid. Applying them to case study data, we find...
