Some examples would be good, to resolve the questions this raises for me. i:12 and 0.1*i:12 are probably good values to use in the examples. It might be that Kip's most recent example, with stems like t, f, s, e, 1 is an example of the X%2 case. But if that's the case, note that X%2 is not the stem here. 10%2 is 5. That said, if the requirement is that the algorithm implicitly pick the stem algorithm based on the data, and if the requirement is to exactly duplicate SAS, and if there's no human understandable complete definition that we can use, what we have is a requirement to use SAS. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
