Kevin Crow wrote in his response to Giulio Rizzoli's request to translate SAS
code into Stata code, "If you could explain what the below syntax does in SAS I
believe I could recreate the results in Stata.
[DO LN_TIME=-1 TO LN_MAX] BY INC,LN_MAX;"
If anyone on the list knows what the answer is to Kevin's question, I'd
appreciate to learn it, too. And I'd be curious as to whether Stata can
perform the analogous operation (whatever it is), either by a straight mimic of
SAS as Kevin illustrates as a courtesy to accustomed SAS users for ease of
transference to Stata, or by a more native Stata implementation that Kit Baum
illustrates.
