针对水工建筑物监测资料中不可避免地夹杂有粗差的情况,将抗差最小二乘法应用于粗差探测,实例分析比较表明,抗差最小二乘法在抵抗一定粗差的同时保持了最小二乘法的优点,其粗差探测结果优于传统方法。
Owing to the monitoring data of hydraulic structure usually containing some gross errors, this paper applies the robust least-squares regression method to gross error discrimination. Example analysis shows that this method can resist a certain degree of gross errors and maintain the advantage of least-square regression method. The result of gross error discrimination is better than that of traditional method.
