However, there are some limitations of this study, such as the not big enough size of sample, the deficiency of processing and analyzing of the data, etc.
尽管如此，本研究尚存许多不足之处，例如，调查对象样本不够大以及研究分析不够全面等。
When the number of sample data points is big enough, the calculating result is rather stable;
当样本点达到一定数目时，计算结果的稳定性好；
It could be generalized to test and estimate the big scale data by training the small sample.
通过对小样本数据的统计学习，能够推广到大规模数据中去进行结果的预测估计。
