You just estimated various models of trend for the U.S. consumer price index. The two models with the lowest SiC were a quadratic model (SIC = -3.10) and a linear model of the natural log of the U.S. consumer price index (SIC = -4.10). Based on these statistics, which model should you choose and why? The quadratic model because it has the higher SIC The log-linear model because it has the lower SIC . It cannot be determined using the SIC in this case because the dependent variables are different It cannot be determined because the depedent variables are highly correlated
