Small increases in agent-based model complexity can result in large increases in required calibration data

Srikrishnan V., Keller K. DOI: https://doi.org/10.1016/j.envsoft.2021.104978 Abstract: Agent-based models (ABMs) are widely used to analyze coupled natural and human systems. Descriptive models require careful calibration with observed data. However, ABMs are often not calibrated in a formal sense. Here we examine the impact of data record size and aggregation on…

A spatial population downscaling model for integrated human-environment analysis in the United States

Hamidreza Zoraghein, Brian C. O’Neill DOI: https://dx.doi.org/10.4054/DemRes.2020.43.54 Abstract: Background: Spatial population models are important to inform understanding of historical demographic development patterns and to project possible future changes, especially for use in anticipating environmental interactions. Objective: We document, calibrate, and evaluate a high-resolution gravity-based population downscaling model for each US…
