| 中文摘要 |
| 本文分析了借助数字计算机进行辨识与建模时，舍入误差给数值计算算来的问题。并因此引入了问题的条件及算法的数值稳定性的概念。进而分析了几种不同的方法求最小二乘估计时问题的条件及其误差。 |
| 英文摘要 |
| It is analysed that the problem caused by rounding errors in parameter identification and modeling, which is solved by using a computer. The concepts of conditioning for a problem and the numerical stability for one algorithm are introduced. Furthermore, the conditional numbers and numerical errors of several algorithms for solving linear squares estimations are discussed. |
