Aiou subject business statistic including the regression topic and here it is explained in detail.
Regression is a statistical measure used In finance, investing and other disciplines that attempts to determine the strength of the relationship between one dependent variable (usually denoted by Y) and a series of other changing variables (known as independent variables).

Regression can help predict sales for a company based on weather, previous sales, GDP growth or other conditions. The capital asset pricing model (CAPM) is an often-used regression model in finance for pricing assets and discovering costs of capital. The general form of each type of regression is:- Y = a + bX+u
Multiple Regression:- Y = a +b1x1 + b2x2 + b3+3 + ………btxt + u
Y = The variable that you are trying to predict (dependent variable)
X = The variable that you are using to predict Y (independent variable)
a = the intercept
b = the slope
u = The regression residual
REGRESSION:- Takes a group of random variables, thought to be predicting Y, and tries to find a mathematical relationship between them. This relationship is typically in the form of a straight line (linear regression) that best approximates all the individual data points. In multiple regression, the separate variable are differentiated by using numbers with subscript.
REGRESSAND:- In regression process the dependent variable is called regressand. It is also called as the response variable or the predict and variable or the dependent variable on the explained variable.
REGRESSOR:- In regressor process the independent variable is called regressor. It is also called as predictor variable or the independent variable or the controlled or explanatory variable.
