In this study, the method of least squares-fit is used to estimate
the regression coefficients in MLR model. Producing a fit using a linear model requires minimizing the sum of the squares of the
residuals. A plot of residuals visually gives a good insight about
goodness of fit. The goodness of fit is also measured by Coefficient
of Determination (R2) and Adjusted Coefficient of Determination
(R2) which indicates how closely obtained values match the
dependent variable of the model. The following equation shows the
regression equation for the proposed linear regression model
