以四川省为例,以火电二氧化硫排放量作为因变量,对不同时间、不同地区的样本采样,采用偏最小二乘回归分析方法,建立自变量的偏最小二乘回归模型。该模型综合了多元回归分析、主成分分析及典型相关分析,很好地解决了由变量多重相关性、... 以四川省为例,以火电二氧化硫排放量作为因变量,对不同时间、不同地区的样本采样,采用偏最小二乘回归分析方法,建立自变量的偏最小二乘回归模型。该模型综合了多元回归分析、主成分分析及典型相关分析,很好地解决了由变量多重相关性、样本点少于自变量个数等引起的模型预测精度不高的问题,同时也避免了使用普通最小二乘回归方法所引起的模型回归系数异常的问题。结果显示,所建模型解释能力强、预测精度高,能为相关部门制定二氧化硫减排措施提供科学的依据。 展开更多
