How can regression analysis be used in forecasting of demand?

Demand forecasters begin a regression analysis by identifying the factors or drivers of demand (Chapter 1), called independent, causal or explanatory variables – that they believe have influenced and will continue to influence the variable to be forecast (the dependent variable).

How does forecast function work in Excel?

The FORECAST function in Excel is used to predict a future value by using linear regression. In other words, FORECAST projects a future value along a line of best fit based on historical data. Where: X (required) – a numerical x-value for which you want to predict a new y-value.
