  "description": "<p dir=\"ltr\">This dataset contains all raw data (CSV) and R software code (RMarkdown notebook) required to reproduce the analyses, figures, and tables presented in the associated manuscript. The study is a comparison of Phomopsis seed decay (PSD) infection rates among different soybean genotypes, with data from an early and late maturity group test in each of five years, 2019-2023. The data consist of binary PSD presence-absence observations on five seeds per plate per genotype, with multiple replicate plates in each test. The statistical analysis is a binomial generalized linear mixed model. Probabilities of infections and their confidence intervals are estimated and compared among genotypes within each test, and code to generate figures and tables follows.</p><p dir=\"ltr\">The following files are included:</p><p><br></p><ul><li>Li_PSD_2019_2023_clean.csv: Primary data file</li><li>data_dictionary.csv: Description of columns in primary data file</li><li>PSD_compareentries_code_supplement.Rmd: RMarkdown notebook with R code to analyze data; a HTML file with the same name is the rendered output of the notebook</li><li>early_and_late_contrast_tables.xlsx: Output of analysis, pairwise contrasts between genotypes</li><li>early_and_late_mean_tables.xlsx: Output of analysis, estimated infection probabilities for each genotype</li></ul><p></p>",
