The possible scenarios for conducting regression analysis to yield valuable, actionable business insights are endless.
Regression analysis in business is a statistical method used to find the relations between two or more independent and dependent variables. One variable is independent and its impact on the other dependent variables is measured. Broadly speaking, there are more than 10 types of regression models.

The earliest form of regression was the method of least squares, which was published by legendre in 1805, and by gauss in 1809. Legendre and gauss both applied the method to the problem of determining, from astronomical observations, the orbits of bodies about the sun (mostly comets, but also later the then newly discovered minor planets).
