##### [Linear Regression] Assessing the Accuracy of the Model

this post talk about how to assess the accuracy of the model, and we take a linear model as an example.

How correct we believe the parameters of the model are always concerned by us. To have more confidence in using methods talked previously, we would like to make a reliable framework, under which the method is always feasible.

Linear regression is a basic idea in statistical or machine learning, especially in supervises learning. The linear regression is a statistical model whose structure is based on the linear combination, and it is usually used to predict some quantitative responses to some inputs(predictors).
