Well, primarily you could help me figure out how to use it :) , but that's more of an issue with not understanding the statistics, as opposed to not understanding the API. We have a large collection of individual data records that indicate success/failure of an operation call, where there are a significant number of possible operations, along with other permutations in the record that associate it with a different "workflow". We can get success/failure ratio of those operations in workflows over particular time periods (15, 60, 180, 1440 minutes, et cetera), but we want to process this data over a much larger time period (30 days or more) to determine what's "normal" for those operations in the various workflows, essentially building percentage ranges for each of those permutations that indicate whether a permutation is "green", "orange", or "red". I've been told by someone who understands the statistics only a little better than me that a beta distribution function could help here, but I won't be able to implement this until we get help from someone who really understands the statistics here. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscribe@commons.apache.org For additional commands, e-mail: user-help@commons.apache.org
