It, by definition, involved squaring of error terms. Thus MSE doesn’t have the same units as the value we want to predict. For example, the MSE for our airfare prediction model is 1870. We cannot report it in dollar terms: an MSE of 1870 is meaningless when the price range is $100 - $1,000. luxury small master bathroom
