| 摘 要： | 在应变监控模型中,各因子之间存在着多重相关性,将会严重影响参数估计、扩大模型误差、破坏模型的稳健性,为了克服多重相关性对模型的干扰.引入了能辨别系统信息与噪声的偏最小二乘回归.研究分析表明,与普通的最小二乘回归相比,偏最小二乘回归模型具有很好的稳定性.

| Abstract: | There is the multiple correlativity between various factors in the monitoring model of stain,it influences the estimation of parameter,expanding model error and damaging model stability.The deflection least square regression,that can distinguishes the system information and distinguishes the system information and the noise,is led to avoid the disturbance of multiple correlativity to the mode.The study indicates that the deflection least square regression has a good stability comparing with the ordinary least square regression. |
