Logistic Regression是一种广泛使用的分类算法,它的主要思想是将输入变量的线性组合映射到0到1之间的概率,用于预测二元输出变量的概率。逻辑回归模型,是一种广义的线性回归分析模型。日常工作生活中我们会遇到很多的1,0分类问题,比如考试通过还是不通过、是否患某种疾病等等这样的问题都可以使用逻辑回归来解决。尽管它被称为“
Logistic regression is a frequently used method because it allows to model binomial (typically binary) variables, multinomial variables (qualitative variables with more than two categories) or ordinal (qualitative variables whose categories can be ordered). It is widely used in the med...
