Definitions:

Least-squares Line

A line of best fit determined by the least squares method, which minimizes the sum of squared vertical distances between the actual data points and the predicted points on the line.

Unbiased Estimator

A statistical estimator whose expected value exactly equals the parameter it estimates.

Intercept

The value of the dependent variable when all independent variables in a regression model are set to zero, representing the model’s starting point.

Least-squares Regression Line

A straight line that best fits the data points in a scatter plot, minimizing the sum of the squares of the vertical distances of the points from the line.
