Y分两个值，0或1，看你具体回归方程式的意义而定。但两个数值肯定都有，你得自己定义0与1
这是哑变量的问题 系数为负数很正常，由你数据本身确定的 另外，从变量选择来看，变量之间应该有很高的共线性
当自变量被赋予一些值时,因变量取0、1的概率就是条件概率,对条件概率进行Logistic回归,称为条件Logistic回归。5个回答 When the independent variable is assigned a number value, the dependent variable is the probability of taking the conditional probability of 0, 1, Logistic regression on the conditional p...
