Discussing with a non statistician colleague, it seems that the logistic regression is not intuitive; Some basics questions like : –Why don’t use the linear model? –What’s logistic function? –How can we compute by hand, step by step to listen what is dealing by the glm function?This...

在说逻辑回归前,还是得提一提他的兄弟,线性回归。在某些地方,逻辑回归算法和线性回归算法是类似的。但它和线性回归最大的不同在于,逻辑回归是作用是分类的。 还记得之前说的吗,线性回归其实就是求出一条拟合空间中所有点的线。逻辑回归的本质其实也和线性回归一样,但它加了一个步骤,逻辑回归使用sigmoid函数转换线...
