我对R很陌生。我正在尝试训练我的数据以进行逻辑回归。尝试构建逻辑回归模型时，我仅使用数值，但不断出现以下错误。
警告信息： glm.fit：发生了数值为0或1的拟合概率
就像我说的那样，很新。
这是我迄今为止尝试过的。
AllMortgage$default <- as.factor(AllMortgage$default)
smp_size <- floor(0.70 * nrow(AllMortgage))
set.seed(12345)
trainindex <- sample(seq_len(nrow(AllMortgage)), size = smp_size)
training <- AllMortgage[trainindex,]
validation <- AllMortgage[-trainindex,]
str(training)
mylogit<-glm(default ~ credit_score + cltv + dti_ratio + upb + ltv + interest_rate + loan_term + num_borrowers,
data=training, family=binomial)
summary(mylogit)
如果我继续构建，则会出现以下错误：
mylogit.probs<-predict(mylogit,validation,type="response")
警告信息： 'newdata'有62537行，但找到的变量有208454行
以下一些示例数据。大约有208563行。

我只想使用训练有素的数据构建一个简单的逻辑回归模型并显示混淆矩阵。
答案 0 :(得分：0)
我完全同意您对Logistic回归所做的工作，从概念上讲完全正确，我无权访问您的数据集，因此我无法测试Logistic。我建议您注意两件事（这是我一直想念的事情）
将数据集加载到R环境中时，请确保充当“响应”的变量是因数，以便它们仅采用1或0值。 您可以像这样手动进行操作（否则，您可以直接在模型中的响应变量前面使用 as.factor 函数）
How you auto convert to factor
请勿使用缩写 尝试指定所有属性：在GLM建筑物中：
mylogit<-glm(AllMortgage$default ~ AllMortgage$credit_score + AllMortgage$cltv + AllMortgage$dti_ratio + AllMortgage$upb + AllMortgage$ltv + AllMortgage$interest_rate + AllMortgage$loan_term + AllMortgage$num_borrowers,
data= your.data, subset = training, family=binomial)
尝试在预测函数中指定所有属性：
mylogit.probs<-predict(mylogit,newdata = validation,type="response")
