| 摘 要： | AR模型在变形监测及其预报中应用广泛,因为系数矩阵和预测值都存在误差,宜采用整体最小二乘法。本文通过一个实例对该方法进行验证,计算结果表明,该方法获得的预测值更加接近实测值,并且比传统的方法更具优势,有较强的理论研究价值和实用价值。 |
| 关 键 词： | AR模型 变形监测 整体最小二乘 参数 |
Total least-squares based on AR model and its applications |
|
| Abstract: | AR model is widely used in deformation monitoring and forecasting,because the coefficient matrix and predictive value both exist errors,the total least-squares should be adopted.In the paper,it used an example to verify this method,and the results showed that the predictive value was much closer to the measured values,and had more advantages than the traditional method.It would have a strong theoretical study and practical value. |
| Keywords: | AR model deformation monitoring total least-squares parameter |
