估计标准误差(Se)是说明实际值与其估计值之间相对偏离程度的指标,主要用来衡量回归方程的代表性。 估计标准误差的值越小,则估计量与其真实值的近似误差越小,但不能认为估计量与真实值之间的绝对误差就是估计标准误差。
计算结果表明:变形统计值与变形监测值吻合较好,统计复相关系数较大,估计标准误差较小。
The calculation results show that the statistic and monitoring value are fairly identical, multiple correlation coefficients bigger and estimated standard error smaller.
