For example, in a regression model in which cigarette smoking is the independent variable of primary interest and the dependent variable is lifespan measured in years, researchers might wo kann ich japanische frauen kennenlernen education and income as additional independent variables, to ensure that any observed effect of smoking on lifespan is not due to those other single equation linear models factors.
