因为预测问题所需的信息都来源于历史数据，任何单一的预测法所获的信息是有限的，使用单一算法要冒较大的风险。
Using the sole algorithm has to brave some extent risk for the information the forecast need is from the history data, and the information that any single forecast algorithm attains is limited.

Taking into account the questionnaire study by the limited information, this study also used a qualitative study of cases in interviews and observation of law.
运用充分统计量法所述理论，可将观测空间由无限压缩至有限，当信号受到高斯白噪声的干扰时可用充分统计量表示被观测量的全部信息并检测出确知信号。
When the signal is interfered with white gaussian noise, the external information of the observed can be expressed by the plenitude statistic, and output signal can also be checked.
