然后将V_K法、均匀度和动态聚类分析法综合在一起，构成了一个适合平面有序地质变量的统计分类系统。
The classifying system is made up of three parts: V_K method, cluster analysis and a new parameter which is defined as degree of uniformity.
三类累积模型要求资料反应变量为有序分类且样本量较大、阳性率不太低。
The data must be ordinal response, enough sample size and not too low event rate for the cumulative models.
