To calculate MAD and MAPE for management’s technique. Introduction: A sequence of data points in successive order is known as time series. Time series forecasting is the prediction based on past events, which are at uniform time interval. Moving average method and trend projections are two of the time series methods, which use weights to prioritize past data.
