Web2 Answers Sorted by: 3 Look at the varsoc command. It gives you 6 different criteria for lag-selection for VAR models but is also applicable to these tests. You would type: varsoc varname. Another way to select the maximum lag length is to use the so-called Schwert criterion: lag length = [ 12 ⋅ ( T 100) 1 4].
WebIn STATA it just requires an option at the end of a “reg” command. ... FGLS is still unbiased and consistent if this is the case (assuming the underlying model satisfies the first 4 Gauss-Markov assumptions).
