广义线性模型(glm)意为利用连接函数将各种分布(正态分布,二项分布,泊松分布)假设下的因变量与自变量想联系起来,使用十分广泛,下面是我之前的笔记,包含letex代码和相应的pdf文件, letex代码: ''' \documentclass{article} \usepackage{paralist} \begin{document} \title{Generate Linear Model Estimation Note} \au...
notes,http://cs229.stanford.edu/notes/cs229-notes1.pdf 前面介绍一个线性回归问题,符合高斯分布 一个分类问题,logstic回归,符合伯努利分布 也发现他们有些相似的地方,其实这些方法都是一个更广泛的模型族的特例,这个模型族称为,广义线性模型(Generalized Linear Models,GLMs) The exponential family 为了介绍GLMs,...

类似的,将前面Linear WLSE改写成适用于GLM的模式,得到 S_w=\sum_{j=1}^N\frac{(y_i-E(Y_j))^2}{Var(Y_j)} For binomial model, Y_j's 独立,并且可以得到以下关系 n_j\pi_j=h(\beta^Tx_j),Y_j\sim Bin(n_j,\pi_j) E(Y_j)=n_j\pi_i; Var(Y_j)=n_j\pi_j(1-\pi_...
首先,我们的故事将从简单而美好的普通 linear model讲起。皇阿玛与爱妃们的关系,可以表达为以下形式,此时,用爱妃的表现来预测皇阿玛会存在一定误差\epsilon。 Y_i=\mathbf X_i^T\beta+\epsilon_i, \epsilon_i\sim iid. N(0,\sigma^2),\sigma^2>0,i=1,...,n ...

指数族分布是广义线性模型(generalized linear models)的核心,参考本书9.3. 指数族分布也是变分推理(variational inference)的核心,参考本书21.2. 9.2.1 定义 概率密度函数(pdf)或者概率质量函数(pmf)$p(x|\theta)$,对$x=(x_1,...,x_m)\in X^m, \theta\in \Theta \subseteq R^d$,如果满...
Marschner Abstract The R function glm uses step-halving to deal with certain types of convergence problems when using iteratively reweighted least squares to fit a generalized linear model. This works well in some circumstances but non-convergence remains a possibility, particularly with a non- ...
