This paper studies the score test for single outlier in general spatial model. Score test statistics are derived under the mean-shift model and the variance-weight model respectively. The approximate distributions of score statistics are obtained when outlier presents in two outlier models mentioned above. Finally, we illustrate our method using a real data of columbus neighborhood crime.
