Adding additional exogenous inputs could improve the fit to the data. But models should not be tuned to fit data by introducing exogenous variables whose sole function is to improve the correspondence of model output to data. Exogenous variables must be justified by significant real world evidence independent of their potential contribution to historical fit.
