Now, we’ll see how in excel, we can fit a regression equation on a scatterplot itself. Simple linear and multiple linear models are the most common. Regression formula is used to assess the relationship between dependent and independent variable and find out how it affects the dependent variable on the change of independent variable and represented by equation y is equal to ax plus b where y is the dependent variable, a is the slope of regression equation, x is the independent variable and b is.

\[\large y=a+bx\] a and b are given by the following. In statistical modeling, regression analysis is a set of statistical processes for estimating the relationships between a dependent variable (often called the 'outcome' or 'response' variable, or a 'label' in machine. Multiple linear regression analysis is essentially similar to the simple linear model, with the exception that multiple independent variables are used in the model.
