Contingency Tables and Fisher's Exact Test Results for Gene Absence Comparisons

Contingency tables and Fisher's exact test results for pairwise comparisons of genes absent from large clades. Statistical significance is denoted by asterisks, with p-values less than 0.01 indicated by two asterisks (**) and p-values less than 0.05 indicated by one asterisk (*). The dataset was authored by Xiao Liang and last updated on May 11, 2026.

Use Cases

• Perform statistical validation of gene absence patterns based on contingency tables.
• Calculate odds ratios to compare the likelihood of gene absence between groups.
• Identify statistically significant associations (p < 0.05 or p < 0.01) between gene groups and clade size.

Strengths

• Statistical significance is clearly annotated with asterisks for p-values less than 0.05 (*) and 0.01 (**).
• The dataset is small (5.5 KB), making it quick to download and inspect.
• It is published under a permissive CC-BY-4.0 license.

Limitations

• The dataset is very small (5.5 KB), indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
