Ordinary Least Squares, or OLS
Ordinary least squares regression is a statistical method of analysis that estimates the relationship between one or more independent variables and a dependent variable. This method estimates the relationship by minimising the sum of the squares in the difference between the observed and predicted values of the dependent variable, which is configured as a straight line.
