WebJan 3, 2024 · Ng and Perron convincingly argue that lag selection should proceed on a common sample space, with the first part of the sample removed to accommodate the maximum lag length.After the optimal lag length has been chosen, Ng and Perron return those observations at the start of the sample that are not lost to lags.This is also the … 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. impact of covid-19 on us automotive industry
