Regression Line. A regression line is simply a single line that best fits the data in terms of having the smallest overall distance from the line to the points. ε y is the mean or expected value of y for a given value of x.
Our regression line is going to be y is equal to we figured out m. It s going to be right over there. In other words it s a line that best fits the trend of a given data.
The sum of the residuals is zero if the model includes an intercept term.
The residuals and x values are. And the slope of our line is 3 7. So it equals 1. Our regression line is going to be y is equal to we figured out m.
