Logistic Regression即逻辑回归,又称作Logistic回归分析,是要预测的变量为有限个离散量(比如2个值)的回归分析问题,可以理解为对样本进行分类的学习方法。 与Linear Regression相似,我们也通过定义Cost Function,依据Gradient Decent的方法来进行Logistic Regression。如果套用Linear Regression的方法,使用 J(θ)=12m∑i=1m(h...
linear regression: Y is continuous Logistic regression:discrete,2-level outcome: purchase or not, gender, yes or no The model is formulated in terms of theprobabilityof success, probablity must lie between 0 and 1. 当然,可以选择使用linear,确实能够拟合出一条直线,但是probability一定在0~1之间,如...
a regression plot (whatever that means), you should do it, but I am not sure that I agree. It seems that logging the Y values will always bring high Y values in closer to the regression curve and automatically result in a better looking picture with fewer "outliers". Might this tend t...

Recently the common practice of fitting power laws using linear regression (LR) on log-transformed data has been criticized, calling into question the conclusions of hundreds of studies. It has been suggested that nonlinear regression (NLR) is preferable, but no rigorous comparison of these two ...
逻辑回归(Logistics Regression) 逻辑回归(Logistics Regression)的目的其实是分类,它的本质是一种二分类方法。 1、Sigmoid 函数 逻辑回归的思想其实非常巧妙,既然我们希望做二分类,那就令这两类的标签为 {0,1}\{0,1\}{0,1}(这里令1为正例,0为负例),对所有的样本 xxx,令 xxx 用来分类的变换值为 zzz (...

The primary focus here is on log-linear models for contingency tables, but in this second edition, greater emphasis has been placed on logistic regression. The book explores topics such as logistic discrimination and generalised linear models, and builds upon the relationships between these basic mod...
