MASE compares the accuracy of a given forecast with that of a naive forecast (e.g., a seasonal naïve or a random walk model). MASE is scale-independent, making it useful for comparing the accuracy of forecasts across different time series with different scales. The formula for MASE is: MASE = mean(|e_t|) /..
