针对山东省阶梯电价的制定,对相关数据进行boxcox变化、正态化、无量纲化及均值化的处理,结合正态分布曲线,运用概率、等距抽样、阈值、回归拟合等方法,建立合适梯度电价标准、用水用电量一元回归等模型,使用Matlab、Excel等软件编程,得出居民用电量所属档次、制定合理的阶梯电价新标准、用电量随用水量变化等结论。
Aimed at the enactment of price ladder in Shandong province, we analyzed the relevant data, processing with boxcox, normalization, non - dimensionallzation and equalization as well as other methods. Besides, we built the medel of appropriate gradient electricity price standards and water - power consumption monadic regression, and combined the normal distribution curve, meanwhile, and applied various techniques, such as probability, interval sampling and threshold value as well as regression fitting. Finally, we successfully drew the conclusion of the level that residents' electricity consumption lies in, and set out the new reasonable standards of price ladder, and figured out how the electricity consumption changes over the water consumption and so on with the help of software program such as Matlab and Excel.
