In this article, an easily digestible mathematical formulation of the multivariate linear regression model is provided. Model fitting by the method of least squares is described, and the application of the fitted-regression model is illustrated through a simple example. The use of software such as ...
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...

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 multivariate linear regression model: 对于重复测量数据来说,p代表重复测量次数;对整群数据来说,p代表群组的个数。该模型中,方程右边有多个自变量/解释变量,方程左边有多个因变量/结局变量,所以多元线性回归既属于Multivariableanalysis,也属于Multivariateanalysis。由于回归模型的自变量存在多个的现象比较普遍,而因变量...
Multivariate Linear Regression 许多机器学习算法的核心是优化。优化算法通常被用来从给定的数据集中寻找一个良好的模型参数。机器学习中最常用的优化算法是随机梯度下降法。在本教程中,您将了解如何使用C语言从头开始实现随机梯度下降,并以此来优化线性回归算法。
