Generalized negative binomial distribution was successfully fitted to all the snail data. The parameters of GNBD from the same bottomlands in different seasons changed differently, and parameters of GNBD from different bottomlands in the same season were not similar even if their snail density were close.

不同季节同一滩地间的广义负二项分布参数的变化不一致，同一季节不同滩地广义负二项分布的参数估计结果即使在钉螺密度相近的情况下也不相近，钉螺生存环境的微小差异可以通过广义负二项分布的参数灵敏反映。

The nonparametric estimation of conditional functional and its derivatives are studied.

It has been verified that the partitioned state estimate is identical with the usual full least square estimate.

这样得到的结果与原来把电力系统状态估计作为一个最小二乘方问题处理所得的结果是一致的。

Statistical analysis was performed by using the Wilcoxon signed rank test to compare quantitative differences between sib pairs and the McNemar test to compare qualitative differences. Generalized estimating equation was used to adjust for within-family correlation in analysis of discordant sib pairs.
