## Can you use regression analysis to predict future sales values?

Regression analysis includes a large group of methods that can be used to predict future values ​​of a variable using information about other variables.

How does regression analysis help in forecasting?

The great advantage of regression models is that they can be used to capture important relationships between the predictor variable of interest and the predictor variables. However, a major challenge is that to generate ex ante forecasts, the model requires future values ​​of each predictor.

What is the regression equation if the company wants to forecast sales?

The regression model equation can be as simple as Y = a + bX, in which case the Y is your sales, the ‘a’ is the intercept, and the ‘b’ is the slope. You would need regression software to run an effective analysis. You are trying to find the best fit in order to discover the relationship between these variables.

How can you make predictions with regression analysis?

Regression predictions are for the mean of the dependent variable. If you think of an average, you know that there is variation around that average. The same is true for the predicted mean of the dependent variable. In the fitted line plot, the regression line is right in the center of the data points.

### How to forecast revenue using linear regression in Excel?

Apart from creating a linear regression line, you can also forecast revenue using Excel’s forecast feature. For example, the company publishes 100 ads next month and wants to forecast its revenue based on the regression. In cell C20, use the formula =FORECAST(B20,\$C\$4:\$C\$15,\$B\$4:\$B\$15).
