Plant-level analysis of sorghum anthracnose dose and mixture assays

This release provides a reproducible, source-experiment-specific workflow for analyzing ordinal inoculum-dose and 1:1 mixed-isolate responses in sorghum anthracnose leaf assays. Contents recovered plant-level ordinal score tables exact conditional Page tests for ordered inoculum-dose trends plant-clustered ordinal GEE sensitivity analyses dose-matched 1:1 mixed-isolate contrasts with exact sign tests family-specific Holm-adjusted P values validation checks, documentation, and citation metadata Plants are treated as the independent experimental units, and disease scores recorded within plant-by-treatment cells are retained as technical subsamples. Published experiments form the primary analysis set; historical blocks are analyzed separately and are used only for within-experiment comparisons. Numerical contrasts with absolute values less than or equal to 1 × 10⁻¹² are treated as ties before sign counting. Figure-generation code is maintained separately and is not included in this public analysis release.
