摘要
在对Ｌｏｇｉｔ判别系数β作似然比检验的基础上，用数值预报产品作为外生变量（预报因子），用极大似然（ＭＬ－）估计，对Ｌｏｇｉｔ判别分析的外生变量进行逐步筛选。
A stepwise selection is made of exogenous variables (predictors) for Stepwise Logit Discrimination Analysis (SLDA) in terms of ML estimations and likehood ratio tests for Logit coefficients β , whereby is constructed a forecasting model for stepwise Logit dynamic statistical interpretation on a daily basis for the June～September typhoon season at Nanjing.
