  • Let's check out the simple linear regression equation once again.

  • Here it is.

  • You have probably heard of the regression line right when we plot the data points on an X Y plane.

  • The regression line is the best fitting line through the data points.

  • Okay, here's a plot with some data points.

  • We plant the line based on the regression equation.

  • The great points that are scattered are the observed values.

  • Be zero, as we said earlier, is a constant and is the intercept of the regression line with Y axis Be one is the slope of the regression line.

  • It shows how much why changes for each unit.

  • Change of X.

  • The distance between the observed values and the regression line is the estimator of the error term Absalon.

  • It's point estimate is called residual.

  • Now, if you draw a perpendicular from an observed point to the regression line, the intercept between that perpendicular and the regression line is a point with a Y value equal toe.

  • Why hat?

Let's check out the simple linear regression equation once again.
