title: 'pigauto: Fill in Missing Species Traits Using a Phylogenetic Tree'
version: 0.10.0.9000
doi: 10.32614/CRAN.package.pigauto
abstract: 'Imputes missing species trait data for comparative analyses by combining
  three sources of information: phylogenetic similarity (closely related species share
  similar traits), cross-trait correlations (observed traits inform missing ones),
  and optional environmental covariates (climate, habitat, geography). 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.'
