Yes, it is interesting that SP1065 uses words like: "original Allan" (page 2, 3, 14) "classic Allan variance" (page 11) "normal Allan variance" (page 16) as a way to distinguish the non- from the overlapping version. We could throw in "traditional", "simple", "back-to-back", "plain".
I agree with the author (W.Riley) that these days ADEV is moving towards being interpreted, and more frequently implemented, as the overlapping variety, but that might take a generation to sink in. I mean, even his own Stable32 program calls the default 2-sample variance "Allan" and if you want the overlapped version you have to click on "Overlapping Allan". So you see why that Allan tool of mine labels the columns adev and oadev? At least there's no ambiguity that way. I should also point out that not all systems can calculate overlapping Allan statistics. Some realtime analyzers, even the fancy TSC boxes for example, cannot do full overlapping (because you need access to the entire data set for that). So plain adev is not dead yet. /tvb _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
