Simple Linear Regression
A linear model can describe the relationship between two variables
Line of "best fit" to the data
What is the best fit?
Squared errors
Best fit minimizes sum of squared errors
Best fit minimizes sum of squared errors
Maximizes likelihood of observed data
Linear regression model
Identify model parameters that minimize squared error, maximize likelihood of data
