Estimate a linear trend model and an exponential trend model for the sample. (Round your answers to 2 decimal places.) Variable Linear Trend Exponential Trend Intercept Standard Error b-2. Calculate the MSE and MAD for the both trends models. (Do not round estimates or intermediate calculations. Round final answers to 2 decimal places.) Linear Trend Exponential Trend MSE MAD
