This time we have thrown even more variables into our model, including the number of bids in each auction (
nBids) and the number of
wheels. Unfortunately this makes a full visualization of our model impossible, but we can still interpret the coefficients.
Call: lm(formula = totalPr ~ duration + startPr + cond + wheels + nBids, data = mario_kart) Coefficients: (Intercept) duration startPr condused wheels 39.3741 -0.2752 0.1796 -4.7720 6.7216 nBids 0.1909
Choose the correct interpretation of the coefficient on the number of wheels:
