Regression analysis is a statistical technique that models the relationship between two or more variables using a mathematical equation (regression equation), enabling prediction of one variable's value based on another. For example, the relationship between temperature and product sales can be approximated by a linear equation, allowing sales to be estimated from a forecasted temperature. It is widely used in business demand forecasting and sales analysis.
