Example of the Ramsey RESET test in practice Consider a simple linear regression model: Y = beta_0 + beta_1 * X + epsilon Where: Y is the dependent variable. X is the independent variable.

Least squares regression line example Suppose we wanted to estimate a score for someone who had spent exactly 2.3 hours on an essay. I’m sure most of us have experience in drawing lines of best fit, ...
