A new criterion for lag-length selection in unit root tests

WebApr 9, 2024 · One problem with the ADF method is the selection of lag length (Schwert 1989). We, therefore, used Akaike’s information criterion to select the optimal lag length (to ensure that the residual was white noise) to mitigate this issue. ... The optimal lags chosen to minimize the residual sum of squares were six, seven and two for the US, the UK ... WebJul 1, 2011 · Well, DF-GLS is an augmented Dickey-Fuller routine, with considerably greater power than the original ADF.

In practice, however, applied researchers usually choose the lag length by data-dependent methods. Often this is done using standard information ships of star trek discovery

"WebAnother way to select the maximum lag length is to use the so-called Schwert criterion: lag length = [ 12 ⋅ ( T 100) 1 4]. A good rule of thumb is to use as many lags as to remove all autocorrelation. Note that Monte Carlo evidence has shown that it is better to include too many lags than too few.
