由于有不同的误差项以及不同类型的离群点，所以分类进行模拟分析，首先是对

Because there are different error terms and different types of outliers, the classification is carried out for simulation analysis. The first is the simulation of several types of error terms, followed by the simulation of abnormal points in the x direction, the simulation of abnormal points in the y direction, and the abnormal points in the xy direction. Point simulation.

Because there are different error items and different types of outlier points, so the classification of simulation analysis, first of all, several types of error items simulation, followed by x direction anomaly point simulation, y direction anomaly point simulation, xy direction anomaly point simulation.

Because there are different error terms and different types of outliers, the classification of simulation analysis, the first is to simulate several types of error terms, followed by X-direction outlier simulation, Y-direction outlier simulation, XY direction outlier simulation.<br>
