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.
