The residual sum of squares denoted by RSS is the sum of the squares of residuals. The residual method of valuation involves a fairly simple calculation that helps property developers to determine a realistic value for the land or property purchase. Then, for each value of the sample data, the corresponding predicted value will calculated, and this value will be subtracted from the observed values y, to get the residuals. Residual = Observed value - Predicted value e = y - ŷ Both the sum and the mean of the residuals are equal to zero. Use of residuals. Equation for Determining Rated Capacity.
