问题四:Logit回归和Logistic回归是一回事吗? 问题五:odds、log-odds、odds ratio和log-odds ratio分别是什么? Part2:Logit模型的原理 1、连接函数(link function) 2、为什么logit模型不能采用最小二乘法? 3、最大似然估计(maximum likelihood)的思路 Part3:如何评价Logit模型拟合程度 1、回归结果中的log likelihood...

其基本原理是通过对自变量(特征)与因变量(结果)之间的关系进行建模,来预测因变量的发生概率。Logit模型使用了逻辑函数(logistic function),将线性组合的自变量值映射到0和1之间的概率值。具体而言,Logit模型通过以下公式进行计算: [ P(Y=1|X) = \frac{1}{1 + e^{-(\beta_0 + \beta_1X_1 + \beta_2X...

Why is the logistic function used to transform the linear combination of inputs ? The simple answer is that we would like to do something similar to what we do in alinear regression model: use a linear combination of the inputs as our prediction of the output. ...
3.4.1 The Logit Link Function The logit link function is used to model the probability of ‘success’ as a function of covariates (e.g., logistic regression). The purpose of the logit link is to take a linear combination of the covariate values (which may take any value between ±∞) ...
