Definition of Regression equation;

Regression equation- it comes under mathematical expression where the, value of dependent variables are predicted from the given independent variables.

Uses of Regression equation;

• Regression equation allows to study the linear relationships between the sets of data by regression model.
• The sets of data are shown in X and Y variable reflecting an independent and dependent variable.  The future events are also calculated by regression equation.
• It is responsible for fitting the data into equations. The past predictions are shown as well as calculated.
• Regression equation is represented to strengthen the relationship between the variables.  

Therefore, Regression equation are also called as Prediction,estimating, and line of average relationship, as the uses of the equation are in the wide variety.
