Line of Regression:
The line of regression is the line that best fits the data in simple linear regression, i.e. the line that corresponds to the "best-fit" parameters (slope and intercept) of the regression equation.
This course will teach you how multiple linear regression models are derived, the use software to implement them, what assumptions underlie the models, how to test whether your data meet those assumptions and what can be done when those assumptions are not met, and develop strategies for building and understanding useful models.
