有些名词不太了解,加括号了.
perform a forecasting task of a numerical sequence which is generated by ARIMA model.
预估由ARIMA模型产生的数字序列.
About one-half of them faced a positive sequence,which contained 20 initial data and 130 separately predicted data generated by ARIMA,based on every twenty data prior to the forecasted period,maximizing R square.
近一半的试验者得到了包含20个初始数据和130个单独由ARIMA预估出来的正序列(positive sequence),这些数据是通过在每二十个在预估序列(forecasted period)之前最大化R的平方(Rsquare)得到的.
