Application of Legendre Polynomial in Annual Electricity Consumption

摘要

Based on statistical data of National Statistical Bureau of China, and giving the least-squares fitting of Legendre polynomial, the data of electricity consumption in per capita from 1983 to 2013 is analyzed by GM (1,1) method and Legendre polynomial least squares method respectively. The results showed that Legendre polynomial least squares fitting method is excellent, per capita energy consumption from 2014 to 2018 is predicted by this method.
