Generally, the value of tolerance is between0and the1, if the value is too small, it indicates that there is collinearity problem between the self-variable and other independent variables.VIFThe larger the value, the more obvious the collinearity problem is, generally less thanTento judge the basis(Neter et al.,1985).
