Logistic regression can be seen as a special case of thegeneralized linear modeland thus analogous tolinear regression. The model of logistic regression, however, is based on quite different assumptions (about the relationship between dependent and independent variables) from those of linear regression....
As we we can see, the above formula reveals the logistic function, and it shows that logistic regression is actually a generalized linear regression model. It is a non-linear classification model by adding a non-linear differentiable link function to the linear model. It can be seen that ln(...
In statistics, a likelihood function (often simply the likelihood) is a function of the parameters of a statistical model given data. 从似然函数的英文定义中可以看到,似然函数是与统计模型中的参数的函数。虽然似然性和概率的意思差不多,但是在统计学中却有着明确的区分: 概率(Probability)使我们平时用的...

非常容易上手的一本书,前半部分用input和datalines让读者专心做统计,后半部分从导入导出数据开始阐述SAS的通用编程语言。这本书用的是SAS8.这里我们只关注它第九章Multiple-Regression Analysis的最后Logistic Regression部分。我这篇的例子即来于此,有简化;
