“…As earlier mentioned, there is high tendency of multicollinearity among the regressors since lags of the same explanatory variable appear in the model (G€ uler, G€ ultay, & Kac ¸iranlar, 2015;G€ ultay & Kac ¸ıranlar, 2015). It becomes difficult to estimate with the conventional OLS when the lag length (p) is known and large (G€ uler et al, 2015;G€ ultay & Kac ¸ıranlar, 2015;Ozbay, 2019;€ Ozbay & Kac ¸ıranlar, 2017). The Almon polynomial lag distribution was recommended as a replacement to the OLS estimator (Almon, 1965).…”
