把上面excel转换为.dta格式,导入stata,然后选“statistics”,然后"Nonparametric analysis ",然后"ROC analysis"然后"test equality of two or more ROC areas",最后就进入ROC分析界面,然后就不知道怎么做了,比如在main里面,reference variable 选哪个?classification 选哪个?等等等,
在statistics--epidemiology and related--ROC analysis-t-est equality of two or more ROC areas,最后就进入ROC分析界面,在main里面,金标准放在reference variable ,classification里诊断方法1,在additional classification variables里放诊断方法2 ,同时选中Graph the ROC curve和Report thr area under the ROC curve。即可,祝好运!
