Answer:
There are a few advantages and disadvantages of these three forecasting sales: moving average, weighted moving average, and regression analysis.
Step-by-step explanation:
The moving average method is the method in which calculation of a overall trend in a data set is done. It is a simple method. But its disadvantage is that this method doesn't take the data outside the average period into accounting.
The weighted moving average method uses exponential method to verify if the past data's effect is correct, Thus, this makes it more accurate in measurements. But, the disadvantage is that it is difficult to use.
The regression analysis method is majorly used for prediction and forecasting. But the disadvantage is its limitation to the linear relationship so it is not able to provide accurate result in case there are more than one variables.
Linear Multiple Regression Analysis method shows relationship between independent and dependent variables. This is best for sales forecast because it is easy to use for decision making and helps solving business problems .
