Thank you for the wonderful and co...Hi EViews team. Thank you for the wonderful and concise work in this three-part post on ARDL models. <br /><br />I've been wondering about this tricky issue for years now, maybe someone can help me out:<br /><br />As we know, the unrestricted CEC regression and the ECM regression are estimated via OLS. As so, I believe that one should be able to replicate the coefficients estimated within the EViews' ARDL window in the Least Square window. Note that for the ECM regression, one should run the long-run equation, save its residuals (Proc/Make Residual Series) and use its lagged form to run the ECM regression (i.e., it is a two-step estimation and I know researchers that did exactly that way before EViews 9 provided the ARDL tool). <br /><br />To make it clearer, for an ARDL (2,2) model, one should be able to replicate the coefficients running an OLS as: d(y) d(y(-1)) d(x(-1)) d(x(-2)) resid(-1), where 'resid' is the residual series obtained from the long-run equation. However, it turns out that all coefficients, standard errors, and most diagnostics are totally different when comparing the built-in ARDL method to the two-step OLS approach. I've tried this several times in the last years, with different data. I’ve tried all OLS, FMOLS, and DOLS and got anywhere near the actual coefficients displayed in the built-in method. For the sake of comparison, there are similar packages in other languages that precisely replicate the ARDL coefficients with the more basic LS regression methods. Any thoughts on that? <br /><br />If you are asking why would I want to run the CEC and ECM regressions via the OLS window, it is because we can’t compute Wald tests on the coefficients of the CEC regression. Note that in View\Representations, the user has access to coefficients from the basic estimation (the one that pops out as soon as you regress the model), which I believe represents the 'intertemporal dynamic estimation' as seen in part 1. In fact, everything one can do in terms of coefficient diagnostics (confidence intervals, variance inflation factor, etc) refers to these coefficients, not to those seen at either CEC or ECM windows.
