What is Specification of spatial models: A simulation study on weights matrices about?

## Abstract The correct specification of spatial models, and especially the choice of the spatial weights matrix, represents a crucial decision for researchers using georeferenced data. However, few guidelines exist on which weights matrix is most appropriate in certain cases. This paper therefore (1) studies the sensitivity of testing and estimating spatial models with different weights matrix specifications and (2) formulates recommendations for researchers applying spatial models regarding model selection and weights matrix specification. The research is based on Monte Carlo simulations with synthetic data. ## Resumen La correcta especificación de modelos espaciales, y especialmente la elección de la matriz de pesos espaciales, representa una decisión crucial para investigadores que estén utilizando datos georreferenciados. Sin embargo, existen pocas recomendaciones acerca de que matriz de pesos es la más apropiada en ciertos casos.
