6、售收入预测销售收入是指企业在生产经营活动中由于销售商品或产品、提供劳务等所得的收入。基本业务收入其他业务收入销售收入预测时间序列时间序列的编制原则时间长短统一原则总体范围统一原则计算方法统一原则总原则:可比原则时间序列变动的形态长期趋势变动(直线、曲线)季节变动(一年以内)循环变动(一年以上)不规则变动分析时间序列的目的描述反映经济规律验证各项方针政策的实施效果推断制定各项方针政策规划经济发展计划平衡国民经济有效高速发展减少政策风险分析时间序列的方法描述方法:平均发展水平时距扩大法移动平均修匀法预测方法
7、:移动平均预测法最小平方法指数平滑预测法自回归预测法季节指数的编制与应用描述方法平均发展水平主要是时点现象求平均问题时距扩大法移动平均修匀法预测方法1、移动平均预测法简单移动平均预测法加权移动平均预测法(请注意权数的选择和应用)最小平方法最小平方法的原理与前面回归分析所用的方法是一样的,其趋势方程为:Yc=a+bt求解参数a、b的标准方程组为∑y=na+b∑t∑ty=a∑t+b∑t2计算举例:年份序号销售量(万件)yt2ty19951996199719981999200012345685.691.096.1101.
