Multivariate Linear Regression(多变量线性回归) 若某个预测的输出结果是由几个因素决定的,如房子的价格有房子的面积、地段和卧室数等决定的。我们分别把这几个叫做特征(feature,或者叫做属性),记为 xj ,表示这是这个任务的第 j 个特征。而 xj(i) 表示第 i 个样本的第 j 个特征。则我们的假设为如下的映射:...
A simple linear regression model: 方程右边仅有一个自变量/解释变量,方程左边仅有一个因变量/结局变量,所以简单线性回归既不属于Multivariable analysis,也不属于Multivariate analysis。 A multivariable or multiple linear regression model: 方程右边有多个自变量/解释变量,方程左边仅有一个因变量/结局变量,所以多元线性...
The multivariate linear regression model expresses a d-dimensional continuous response vector as a linear combination of predictor terms plus a vector of error terms with a multivariate normal distribution. Let yi=(yi1,…,yid)′ denote the response vector for observation i, i = 1,...,n. In...

We consider the class of heavy-tailed ...
