Handles continuous measurements, counts, binary variables, ordered categories, unordered categories, bounded proportions, zero-inflated counts, and compositional multi-proportion data in a single call. The method blends a phylogenetic baseline with a graph neural network correction; a per-trait gate calibrated on held-out data ensures the network only contributes when it improves on the baseline. Provides conformal prediction intervals (95% coverage) for continuous, count, and ordinal traits and supports Rubin's-rules multiple imputation for downstream inference, including tree-uncertainty propagation via posterior tree samples. Tested up to 10,000 species. Bundled datasets include a 300-species and a 9,993-species AVONET bird trait + BirdTree phylogeny subset.https://github.com/r-universe/itchyshin/actions/runs/26787407268Mon, 01 Jun 2026 21:54:40 GMTpigauto0.10.0.9000successhttps://itchyshin.r-universe.devhttps://github.com/itchyshin/pigautocommon-pitfalls.Rmdcommon-pitfalls.htmlCommon pitfalls / FAQ2026-05-10 11:06:342026-05-12 17:26:16getting-started.Rmdgetting-started.htmlGetting started with pigauto: Phylogenetic Imputation via Graph AUTO-encoders2026-04-06 22:25:322026-05-12 17:26:16gnn-architecture.Rmdgnn-architecture.htmlGNN architecture and the math behind pigauto2026-05-18 15:46:532026-05-26 22:33:09mixed-types.Rmdmixed-types.htmlMixed-Type Trait Imputation2026-04-07 11:50:292026-05-12 17:26:16tree-uncertainty.Rmdtree-uncertainty.htmlPropagating Tree Uncertainty2026-04-18 14:01:482026-05-12 17:26:16
