Linear Regression deals with gathering the output of a dependent variable by evaluating how the independent variable is behaving under similar circumstances. Linear regression is based on the straight line equation which is y = mx+c. Here, y is the dependent variable and x is the independent variable.
Linear Regression is based on Ordinary Least Square Regression. It is important to know the following types of variables:
Dependent Variable – A Dependent Variable is the variable to be predicted or explained in a regression model. This variable is assumed to be functionally related to the independent variable.
Independent Variable – An Independent Variable is the variable related to the dependent variable in a regression equation. The independent variable is used in a regression model to estimate the value of the dependent variable.
