• Model the temporal spread of pellagra across Southern United States counties
• Examine economic or agricultural variables correlated with pellagra prevalence

Strengths

• Data is associated with a peer-reviewed publication in The Journal of Economic History
• Dataset is tagged with specific historical and regional identifiers like 'Otherpellagra' and 'Southern United States'
• The replication package is versioned (Version 4), indicating maintenance

Limitations

• The specific data structure, including column names, row count, and file formats, is unknown
• The dataset's temporal coverage and geographic granularity are not specified
• Data may be historical and not reflect contemporary conditions
