1) Omitting relevant variables from the regression analysis can bias the regression results. 2) If a nonlinear regression equation provides a better fit to the actual data, but a straight-line regression is estimated, the estimated straight-line regression will have a greater R2 than the R2 from the nonlinear regression. 3) If a scatter plot of the data points for the price and quantity demanded appear to have a convex (bowed inward) shape, estimating a log-linear demand curve will likely yield a R2 that is greater than the R2 from a straight-line demand curve. 4) Using Excel, Best Paints estimates the log-linear weekly demand function for their gallon sized paints to be ln Qd = 16.23 - (1.85 × ln P); at a price of $35, the predicted quantity Qd ^ is 15,562.29. 5) A nonlinear demand curves have positive slope.
