The following three equat

The following three equations were estimated using the 1,534 observations in 401K.RAW:prate = 80.29 + 5.44 *mrate + .269 *age – .00013 * totemp(.78) (.52) (.045) (.00004)R^2 = .100,—R ^2 = .098.prate = 97.32 + 5.02 mrate + .314 age – 2.66 * log(totemp)(1.95) (0.51) (.044) (.28)R^2 = .144,—R ^2 = .142.prate = 80.62 + 5.34 mrate + .290 age – .00043 totemp(.78) (.52) (.045) (.00009)+ (.0000000039 totemp) ^ 2(.0000000010)R^2 = .108,—R ^2 = .106.Which of these three models do you prefer? Why?
