摘要
利用Probit、Logit和Extreme三种二元选择模型研究蠓虫分类问题,并用极大似然法进行参数估计,所得方法具有较高的拟合优度和较好的预测效果,可以用于有效鉴别两类蠓虫。
The classification problem of midges is studied by using three kinds of binary choice models： Probit,Logit and Extreme Model,and the Method of Maximum Likelihood is used for the parameters estimation.The results show that the binary choice models have high goodness of fitting and good prediction accuracy,two kinds of midges can be classified by means the binary choice models.
