What are the advantages of linear regression?

linear regression Advantages 1- Fast Like most linear models, Ordinary Least Squares is a fast, efficient algorithm. You can implement it with a dusty old machine and still get pretty good results. 2- Proven Similar to Logistic Regression (which came soon after OLS in history), Linear Regression has been a breakthrough in statistical applications.
