Weighted-moving-average-method
- 加权移动平均法就是根据同一个移动段内不同时间的数据对预测值的影响程度,分别给予不同的权数,然后再进行平均移动以预测未来值。 加权移动平均法不像简单移动平均法那样,在计算平均值时对移动期内的数据同等看待,而是根据愈是近期数据对预测值影响愈大这一特点,不同地对待移动期内的各个数据。对近期数据给予较大的权数,对较远的数据给予较小的权数,这样来弥补简单移动平均法的不足。-Weighted moving average method is according to the degree of infl
The-trend-of-moving-average-method
- 趋势分析法(trend analysis approach) 又叫比较分析法、水平分析法,它是通过对财务报表中各类相关数字资料,将两期或多期连续的相同指标或比率进行定基对比和环比对比,得出它们的增减变动方向、数额和幅度,以揭示企业财务状况、经营情况和现金流量变化趋势的一种分析方法。采用趋势分析法通常要编制比较会计报表。-The trend analysis method (trend analysis approach) is also called the method of comparat
Single-exponential-smoothing
- 一次指数平滑法是指以最后的一个第一次指数平滑。如果为了使指数平滑值敏感地反映最新观察值的变化,应取较大阿尔法值,如果所求指数平滑值是用来代表该时间序列的长期趋势值,则应取较小阿尔法值。同时,对于市场预测来说,还应根据中长期趋势变动和季节性变动情况的不同而取不同的阿尔法值,一般来说,应按以下情况处理:1.如果观察值的长期趋势变动接近稳定的常数,应取居中α值(一般取0.6—0.4)使观察值在指数平滑中具有大小接近的权数;2.如果观察值呈现明显的季节性变动时,则宜取较大的α值(一般取0.6一0.9),
