  2. Concept of Linear Regression

  3. Given Example

  4. Scatter Plot of given data set

  5. Fitted Regression Curve

  6. Calculating Error • Once the fitted regression line is known, the fitted value of corresponding to any observed data point can be calculated. For example, the fitted value corresponding to the 21st observation in above Table is: • The observed response at this point is y21 = 194 Therefore, the residual at this point is:
