AboutTranscript. In linear regression, a residual is the difference between the actual value and the value predicted by the model (y-ŷ) for any given point. A least-squares regression model minimizes the sum of the squared residuals.The LSRL passes through the point (\(\ \bar{x},\bar{y}\)). It follows that the y-intercept of the LSRL is given by \(\ b = \bar{y} - \bar{x}m = \bar{y} - \bar{x}r \frac{s_y}{s_x}\) It is possible to find the (coefficients of the) LSRL using the above information, but it is often more convenient to use a calculator or other electronic tool.
