Mean crime count per 6-h slot and 100-m grid. c Basic spatial distribution of crime all counts per 6 h-slot and 100 m gird. Prediction from basic GAM (Model 1, Table 2). The model includes fixed terms for season dummies, time of day dummies, and linear terms for temperature, rain, and wind. See Table 2 for fixed term estimates, significance of smoothers, and model fit statistics
