Regression Analysis

Regression analysis is a statistical technique utilized to assess the relationships between a dependent variable and one or more independent variables. It aids in understanding how variations in independent variables affect the dependent variable's value, commonly applied for forecasting and prediction.

This method is extensively employed for forecasting and prediction. Companies can estimate future sales based on historical data or economic trends. In finance, it plays a crucial role in asset valuation and in analyzing how market dynamics affect stock prices.

Additionally, it serves as a fundamental tool in disciplines such as economics and public health. It enables researchers to deduce possible causal links between variables, such as the effect of a policy on a community. This facilitates data-informed decision-making and the evaluation of theories using measurable data.

There are various forms of regression analysis, each tailored for specific types of data and relationships. The selection of a method is influenced by the characteristics of the dependent variable and the presumed connections among variables. The most prevalent types range from simple linear models to more intricate, non-linear methods.

Although both methods analyze relationships among variables, they fulfill different analytical functions and should not be confused with one another.
