Would anyone know how to use SQLITE to calculate the streakedness of data? The definition of streakedness is how many deviations away from the mean(i.e running average a numerical data streak is Thank you for your help.
A variable R can be used to indicate how many deviations away from the mean a particular streak is. According to the disclosed embodiment, the level of a streak can be defined not just in (integer*deviation) distances from the mean but also as (integer*fraction_of_deviation) distances. To accomplish this, a variable R-factor can be used. The R-factor indicates the separation between two successive R-levels in terms of a fraction of the deviation. By varying the R-factor, streaks can be ranked as required. However, the "credibility" of the streak should also be considered, and included in a ranking mechanism. The deviation within the streak is an obvious measure of how staggered the data is within the streak. A good streak should be less staggered, or in other words, have less deviation. For this reason, a very high level streak is considered to be good, even if its deviation is more than what would normally be desired. Thus, while the level R influences the ranking positively, the deviation within the streak influences it negatively. _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
