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.
统计量的标准误差表示该统计量作为总体参数的估计的准确程度。
The standard error of a statistic provides an indication of how accurate an estimate it is of the population parameter .
