Then we fit family income distribution with three-parameter Iognormal distribution, and using iteration method, we determine three parameters of lognormal distribution.
然后，把家庭收入拟合于三参数的对数正态分布，并用迭代的方法求出分布的参数。

Based on the embedding theorem of fuzzy sets, we consider a sort of parameterfamily for the distribution of imprecise data and propose the corresponding point estimation approach.
基于模糊集的嵌入定理，对非精确数据的分布提出一种统计参数族，并给出相应的点估计方法。

For the phase of product configuration in modular design, a process of product module configuration set is put forward based on the feature parameter model of module family.
