Second-Order Residual Analysis of Spatiotemporal Point Processes and Applications in Model Evaluation
时空点过程的二阶残差分析及其模型评价应用
Summary The paper gives first-order residual analysis for spatiotemporal point processes that is similar to the residual analysis that has been developed by Baddeley and co-workers for spatial point processes and also proposes principles for second-order residual analysis based on the viewpoint of martingales. Examples are given for both first- and second-order residuals. In particular, residual analysis can be used as a powerful tool in model improvement. Taking a…
