然后，当我想使用此代码拟合模型时：
fit = lrm(OUTCOME ~ .-1,data = cs_data_train,x=T, y=T)
它出错了：
lrm.fit中的奇异信息矩阵（rank = 148）。违规 变量：DataCRMSanoflore.HOURS_INSCR.1 lrm中的错误（OUTCOME~。 - 1，data = cs_data_train，x = T，y = T）：无法使用“lrm.fit”拟合模型
我搜索但无法解决此问题。谢谢你的帮助！
修改
如下面的评论所述。我需要删除每个相关变量中的一个。所以我写了这段代码：
> highlyCorrelated <- findCorrelation(correlationMatrix, cutoff=(0.7),verbose = FALSE)
> print(highlyCorrelated)
[1] 21 20 26 15 18 17 22 16 25 19 23 24 6 9 7 10 28 2
> important_var=colnames(DATA_BASE[,-highlyCorrelated])
> important_var
[1] "DataCRMSanoflore.Year_Sales" "DataCRMSanoflore.Date_Sales" "DataCRMSanoflore.HOURS_INSCR.1"
[4] "DataCRMSanoflore.Day_Creation_Sales" "DataCRMSanoflore.MEAN_PURCHASE" "OUTCOME"
> DATA_BASE<-DATA_BASE[,-highlyCorrelated]
> str(DATA_BASE)
'data.frame': 5775 obs. of 6 variables:
$ DataCRMSanoflore.Year_Sales : num 2 1 2 1 2 1 1 1 1 2 ...
$ DataCRMSanoflore.Date_Sales : num 13 3 10 22 23 26 13 1 12 2 ...
$ DataCRMSanoflore.HOURS_INSCR.1 : num 17 14 18 17 16 11 22 14 23 17 ...
$ DataCRMSanoflore.Day_Creation_Sales: num 13 11 15 2 31 26 23 1 5 2 ...
$ DataCRMSanoflore.MEAN_PURCHASE : num 0 71.8 50.7 18.7 0 ...
$ OUTCOME : Factor w/ 2 levels "0","1": 1 1 2 1 1 1 2 2 1 1 ...
但我得到同样的错误
lrm中的错误（OUTCOME~。 - 1，data = train，x = T，y = T）：Unable 使用“lrm.fit”来适应模型
这真奇怪！
我该如何解决这个问题？
