Hi, community.
I have some questions regarding ARDL model in the form of UECM(Dynamic panel data).I use this technique to estimate EKC Hypothesis for panel of 16 countries.I wonder if I can use this method in the presence of random effects (for example, by using GLS).I also would like to know if I should implement specification tests(autocorrelation, heteroskedasticity and contemporaneous correlation)like fixed effects model.I really appreciate your advice.
