Moreover, many people suffer ambiguity in understanding these two.

These techniques form a core part of data science and machine learning where models are trained to detect these relationships in data. Python and R are both powerful coding languages that have become popular for all types of financial modeling, including regression.

The analysis is also used to forecast the returns of securities, based on different factors, or to forecast the performance of a business. Essentially, the CAPM equation is a model that determines the relationship between the expected return of an asset and the market risk premium. For example, the statistical method is fundamental to the Capital Asset Pricing Model (CAPM). Regression analysis comes with several applications in finance. If the independent variables are highly correlated with each other, it will be difficult to assess the true relationships between the dependent and independent variables.
