无论在学术界,还是在工业界,Logistic Regression(LR,逻辑回归)模型[1]是常用的分类模型,被用于各种分类场景和点击率预估问题等,它也是Max Entropy(ME, 最大熵)模型[2],或者说Softmax Regression模型[3],在二分类的一种特例。 用X=(x1,x2,…,xk)表示k维样本,用β=(β0,β1,β2,…,βk)表示k+1维...

(2001). Logistic regression in rare events data.Political analysis,9(2), 137-163. 【第一二章总结】 什么是稀有事件数据? 数据中因变量是二元的,且【发生】的数量远远小于【不发生】的数量,即【1】的数量远远小于【0】。 “这种因变量被认为难以解释和预测” 为什么? 1. 统计流程statistical procedures ...
This paper studies binary logistic regression for rare events data, or imbalanced data, where the number of events (observations in one class, often called cases) is significantly smaller than the number of nonevents (observations in the other class, often called controls). We first derive the ...
