ARDL model

[sawsen rachida]

Please, does the ARDL procedure always require writting the variables without lags in the ARDL cointegration formula, in the form Xt (i.e. Xt in the place of X(t-1)?

but if you want to estimat ARDL(1, 0)

Using OLS: To do the bounds test, what equation from ((1) or (2)) is we taking?

ls d(Y) c Y(-1) X(-1) ......... (1)

ls d(Y) c Y(-1) X ......... (2)
i would appreciate your quick responce please ,
thank you
