In R, multiple linear regression is only a small step away from simple linear regression. In fact, the same lm() function can be used for this technique, but with the addition of a one or more predictors. This tutorial will explore how R can be used to perform multiple linear regression...
http://ufldl.stanford.edu/tutorial/ 2 Linear Regression 理论简述 对于线性回归Linear Regression,恐怕大部分童鞋都了解。简单的说 线性回归问题就是一个目标值y取决于一组输入值x。我们要寻找一个最合适的如果Hypothesis来描写叙述这个y与x的关系。然后利用这个Hypothesis来预測新的输入x相应的y。
In this chapter, you will learn when to use linear regression, how to use it, how to check the assumptions of linear regression, how to predict the target variable in test dataset using trained model.
