基于定权的多因子线性拟合方法研究

摘要

By synthesizing the characteristics of curve fitting and multiple factors linear fitting, the multiple factors linear fitting model was presented to dispose the displacement monitoring data, realized the modeling process, and compared with the result of multivariate linear regression. Then by analysing the model of displacement monitoring data to verify the feasibility of the application of multiple factors linear fitting model to subsidence monitoring.%通过综合曲线拟合与多因子线性拟合的特点,提出基于定权的多因子线性拟合方法用于多因子变形监测数据处理,实现基于定权的多因子线性拟合模型的建模过程,并与多元线性回归结果进行比对,同时对沉降变形监测的沉降量进行预测分析,验证模型的可行性和实用性.
