Perhaps the most fundamental type of R analysis is linear regression. Linear regression can be used for two closely related, but slightly different purposes. You can use linear regression to predict ...

We will also study the properties of least squares, and describe some goodness of fit metrics for linear regression models. In this module, we will identify how models can predict future values, as ...

Prediction intervals will be particularly inaccurate ... Statistical inference for linear regression relies heavily on the variance estimate, MSE, and is therefore influenced by any factor ...
