Volcanic Clast Source Assignment via Linear Discriminant Analysis

Linear Discriminant Analysis results probabilistically assigning volcanic clast samples to sources between the Villa Draghi and Via Scagliara di M. Castellone quarries. The dataset, created by Simone Dilaria, is a 5.5 KB Excel file last updated in April 2026. Discriminant functions with a p-value < 0.05 are considered statistically significant at the 95% confidence level.

Use Cases

• Classify volcanic clast provenance based on statistical discriminant functions.
• Validate geological sourcing models between specific quarries using probabilistic assignments.
• Assess the statistical significance of discriminant functions for material analysis.

Strengths

• Statistical significance of discriminant functions is explicitly defined (p-value < 0.05 at 95% confidence).
• Dataset is openly licensed under CC-BY-4.0.
• File size is small (5.5 KB), facilitating quick download and inspection.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's 5.5 KB size indicates a very limited scope of samples or variables.
