Coral Sediment Environmental Variable Significance from dbRDA Analysis

Two statistical model summaries present results from a distance-based Redundancy Analysis (dbRDA) on coral-associated sediment samples. The data includes degrees of freedom, sum of squares, F statistics, and p-values for retained environmental variables. Ana Olmos Pin authored this 5.5 KB dataset, which was last updated in April 2026.

Use Cases

• Identify which environmental variables (e.g., sediment properties, coral trophic state) significantly explain variation in bacterial communities using the reported F statistics and p-values.
• Compare model robustness by analyzing the sum of squares and degrees of freedom between the full sample set and the subset with outliers removed.
• Validate or replicate the backward model selection process (ordistep) for dbRDA in coral reef sediment studies using the provided final model parameters.

Strengths

• Dataset provides specific statistical outputs (F statistic, p-value) for model interpretation.
• Includes results for two distinct sample analyses: a full set and a subset with outliers removed for comparison.
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• Very small dataset at 5.5 KB, containing only summary statistics with no raw sample-level data.
• Unknown row count and specific column names limit detailed re-analysis.
• Geographic origin of the coral sediment samples is not specified.
