多变量线性回归(Multivariate Linear Regression) (一)多维特征(Multiple Features) 在学习单变量线性回归的时候,学习的例子是房价预测,我们选取的特征只有一个---房子的面积。但在实际中,影响房价的因素远不止房子的面积,还有房间的数量,楼层的数量,房龄等等,所以,在原有基础之上,我们增加上这些变量特征,使得问题更符...
一、多变量线性回归(Multivariate Linear Regression)1.1多维特征(Multiple Features)目前为止,我们探讨了单变量/特征的回归模型,现在我们对房价模型增加更多的特征, 例如房间数楼层等,构成一个含有多个变量的模型,模型中的特征为(x 1 ,x 2 ,…,x n )。 增添更多特征后,我们引入一系列新的注释: n 代表特征的数量...

Proof: These properties are the multiple regression counterparts to Properties 2, 3 and 5f ofRegression Analysis, respectively, and their proofs are similar. Observation: From Property 2 and the second assertion of Property 3, which is the multivariate version of Property 1 ofBasic Concepts of Co...

The equation for multivariate linear regression is more generalized and takes the matrix form: Y = X × B Where Y is the matrix of dependent variables, X is the matrix of independent variables, and B is the matrix of coefficients. Each column of Y represents a different dependent variable,...
Regression analysis is one of the most powerful multivariate statistical technique as the user can interpret parameters the slope and the intercept of the functions that link with two or more variables in a given set of data. There are two types of regression multilinear regression and simple lin...
