test of goodness

Test of goodness of fit proved that when the index of aphid degree was less than 80 and the samples were more than 100, the quantity estimation accuracy was as high as 90%.

对该分级标准及回归模型的拟合检验结果表明，当蚜情指数小于80、抽样量在100株以上时，对蚜量的估计可达90%的准确度。

Results: a general framework of the model is established. The property of covariance density and the goodness of fit test are given.

结果：提出了模型的一般框架，并给出了协方差密度的性质以及模型的拟合优度检验。

Furthermore, it has been verified to have higher goodness-of-fit than graphical methods by comparing the ks test statistics for 10 CNN networks.

此外，通过对10个CNN网络进行KS检验统计量的比较，证实该方法比图形方法具有更好的拟合效果。
