Regression Analysis
In marketing, the regression analysis is used to predict how the relationship between two variables, such as advertising and sales, can develop over time. Business managers can draw the regression line with data (cases) derived from historical sales data available to them.
The purpose of regression analysis is to describe, predict and control the relationship between at least two variables.
