http://korora.econ.yale.edu/phillips/pubs/art/p1460.pdf WebThe analysis in Cavaliere and Taylor (2008, 2009b) is based on the use of a lag length in the augmented Dickey–Fuller (ADF) test regression which is a deterministic function of the sample size. In practice, however, applied researchers usually choose the lag length by data-dependent methods. Often this is done using standard information 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. high standard supermatic deluxe c1200
