The concept of regression

Regression is (in mathematics) the dependence of the mean value of one (it) random variable on another random variable. In a functional relationship, each value of a quantity corresponds to one value of that quantity, while in a regression relationship, the value of x in different cases corresponds to different values. The concept of regression is introduced not only for random variables, but also for random vectors. The term regression was introduced by the English scientist F. Galton (1886). Regression is an important mathematical tool in the study of natural and social phenomena.

Regression captures the correlation between variables observed in a data set and quantifies whether those correlations are statistically significant or not.

The two basic types of regression are simple linear regression and multiple linear regression, although there are non-linear regression methods for more complicated data and analysis. Simple linear regression uses one independent variable to explain or predict the outcome of the dependent variable Y, while multiple linear regression uses two or more independent variables to predict the outcome (while holding all others constant).
Regression can help finance and investment professionals as well as professionals in other businesses. Regression can also help predict sales for a company based on weather, previous sales, GDP growth, or other types of conditions. The capital asset pricing model (CAPM) is an often-used regression model in finance for pricing assets and discovering the costs of capital.
