The nature of causality is systematically investigated in several academic disciplines, including philosophy and physics. In academia, there are a significant number of theories on causality; The Oxford Handbook of Causation (Beebee, Hitchcock & Menzies 2009) encompasses 770 pages.Among the more influential theories within philosophy are Aristotle’s Four causes and Al-Ghazali’s.

Despite the fact that I’ve cast this problem in terms of the vectors used in multiple regression analysis. you therefore need to be able to show that causality exists and what its direction is.

Use regression analysis to describe the relationships between a set of independent variables and the dependent variable.
