Financial Planning and Forecasting: Using Regression to Improve Forecasts Regression analysis is a statistical technique that fits a line to observed data points so that the resulting equation can be used to forecast other data points. It is useful in excess capacity and economies of scale situations. Economies of scale occur when the ratio of asset to sales will change as the size of the firm increases. Regression analysis can lead to improved financial forecasts and better information which can...

What is the most difficult problem for a forecaster using multiple causal regression? Multiple Choice Monitoring the economic time series. Identifying the dependent variable. Finding relevant independent variables with the right periodicity and covering the historic period matching the data. Determining the degrees of freedom necessary for the model and making certain they are in line with the demand planning models.
