MATLAB Workshop 15 - Linear Regression in MATLAB 线性回归分析
(See MATLAB® code example and how to use the mldivide operator to estimate the coefficients for a simple linear regression.) Multiple linear regression (models using multiple predictors): This regression has multiple Xi to predict the response, Y. An example of this equation is: Y=β0+β1...
MATLAB 实现 参考文献 回到顶部 线性回归解决的问题 “线性回归” 试图学得一个通过属性的线性组合来进行预测的函数,以尽可能准确地预测实值输出标记,一般形式为 f(x)=wTx+b(1)(1)f(x)=wTx+b 其中xx 表示一组属性,长度为 nn 的列向量. w=(w1;w2;w3;...;wn)w=(w1;w2;w3;...;wn) 表示一组参...
In MATLAB, you can find B using the mldivide operator as B = X\Y. From the dataset accidents, load accident data in y and state population data in x. Find the linear regression relation y=β1x between the accidents in a state and the population of a state using the \ operator. The...
