Volcanic Clast LDA Results for Quarry Source Assignment

Simone Dilaria's dataset contains the results of a Linear Discriminant Analysis (LDA) performed on volcanic clast samples. The analysis probabilistically assigns samples to sources between the Villa Draghi and Via Scagliara di M. Castellone quarries, using a discriminant function considered statistically significant at a 95% confidence level (p-value < 0.05). The dataset was last updated on April 13, 2026.

Use Cases

• Validate the statistical significance of the discriminant function for source assignment based on the reported p-value.
• Compare probabilistic assignments of volcanic clasts between the two specified quarries.
• Use the LDA model results as a reference for classifying new volcanic samples from the same region.

Strengths

• The discriminant function is reported as statistically significant at a 95% confidence level (p-value < 0.05).
• Dataset is licensed under CC-BY-4.0, allowing for open sharing and reuse.
• File size is 5.5 KB, indicating a compact and focused dataset.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
