So if I understand correctly the rows of that matrix refer to lag orders 1 through the order given in the 'var' command, and the columns are AIC, BIC, HQC, as in the printout. Of course I could check that myself, but I haven't updated by build yet. (As an aside question, couldn't the criteria also be given for zero lags?) That would mean that to recover the lag length recommendation from --lagselect I could do: mylagorder = iminc($test)[crit] where crit=1 means AIC, crit=2 BIC, and crit=3 HQC. Thanks, sven
