Hello Solarin and all respected researchers,
I just catch you here in the forum. I would like to ask about ARDL. im doing on it. After the ARDL estimation and all the diagonstic check up, on both the Longrun and cointegration form, and the estimation, i have got insignificant coefficients via pvalue and i suspect, it has some endogeneity problem and i think to get ride off the time t variables and to see only the lagged effect would the solution and thus, How could i get ride off it? i am unable to do that by any means. i need help please.?

Thanks
