针对大坝观测数据统计回归计算中出现的数据共线性和观测数据中的粗差问题,应用奇异值分解算法计算大坝统计模型中的系数。计算结果表明,基于奇异值分解算法的模型能够在这2个常见问题上均取得较满意的结果。
Aiming at the colinearity of data and gross-error existing in dam monitoring data regression analysis,the Singular Value Decomposition(SVD) algorithm is applied to estimate the coefficients of the dam statistic model.The example shows that the algorithm is effective in solving the two problems.
