求翻译：上式表明当t向前移动一个时期，就增加一个新近数据，去掉一个远期数据，得到一个新的平均数，逐期向前移动，所以称为移动平均法。由于移动平均可以平滑数据，消除周期变动和不规则变动的影响，使长期趋势显示出来，因而可以用于预测，预测模型为Xt+1=Mt，即以第t期的移动平均数作为第t+1期的预测值。是什么意思？

The above equation shows that a period of time t to move forward, to increase a recent data, to remove a long-term data, a new average, by period to move forward, so called the moving average method. Moving average to smooth the data, to eliminate the impact of the cycle changes and irregular change

On the T-Mobile a forward on the increase, a new data, and then remove a long-term data, get a new one, the average move forward, it is called moving average. The moving average can be smoothed data, eliminating cycle changes and does not rule changes, the long-term trend shows up, and can be used t

The above equation indicated when a t forward motion time, increased one recently the data, removed a forward data, obtained a new mean value, by time forward motion, therefore was called the moving average method.Because moves may equally the smooth data, eliminates the cyclical change and the irre

Indicates that when t moved forward on a period, a newly added data, remove a long term data, get a new average, by moving forward, it is called moving average method. Due to the moving average to smooth data, eliminate the cycle changes and influence irregular movements of, the long-term trend to a
