BKVerify: Consistency Auditing of Reported Plant Breeding Statistics
Audits published or draft plant breeding tables for internal
arithmetic consistency. Analysis of variance tables, precision statistics
and genetic variability parameters are jointly over-determined by exact
algebraic identities; 'BKVerify' recomputes every derivable quantity using
rounding-interval arithmetic and reports a value as inconsistent only when
no combination of values inside the reported rounding intervals can satisfy
the identity. The package deliberately restricts itself to relationships
that hold irrespective of which variance-component definition an author
adopted, so that flagged results reflect arithmetic inconsistency rather
than methodological disagreement. Implemented checks cover analysis of
variance internal structure, coefficient of variation, standard error of
mean and critical difference, the genetic advance identity of Johnson,
Robinson and Comstock (1955) <doi:10.2134/agronj1955.00021962004700070009x>,
the relation between genotypic and phenotypic coefficients of variation and
broad-sense heritability, and admissibility of reported correlation
matrices.
