摘要
偏最小二乘回归能较好地解决自变量之间的相关性问题,克服了变量多重相关性在系统建模中的不良作用.同时用这一方法建立的泉流量模型,可进行流量预报.且以黑龙洞泉为例,通过计算、拟合、分析,说明建立的泉流量模型具有较好拟合性和稳定性.
Partial least squares regression method can resolve the problem of multicollinearity among variables, and overcome the bad effect of the multicollinearity among variablesin the system modeling. The model of the spring flow with partial least squares method is proposed in order to solve the prediction question about the spring flow, and the detail calculation steps are given. It is shown that the spring flow model founded is preferably fitting and stability for the case of the Black Dragon Cavity by calculating,fitting and analyzing.
