Rhesus Macaque Infant Mortality and Life History Data from Cayo Santiago

Three linked datasets from a study on early life mortality in free-ranging rhesus macaques. The data was collected by D. Susie Lee from the Cayo Santiago population and includes variables like infant body mass, maternal age and rank, and birth timing. Each dataset adds a specific outcome variable: time to death, maternal birth skipping, or last suckling week.

Use Cases

• Modeling infant survival time based on standardized body mass and maternal characteristics.
• Predicting maternal reproductive skipping in the following year based on infant traits and maternal rank.
• Analyzing weaning behavior timing using the last observed suckling week.
• Studying the relationship between birth season timing and early life outcomes.

Strengths

• Data includes three distinct but related datasets for multi-faceted analysis.
• Variables are clearly defined and standardized, as described in the associated research paper.
• Data originates from a long-studied, free-ranging primate population on Cayo Santiago.

Limitations

• Row count and overall data scale are unknown, which may limit suitability assessment.
• One dataset (weight_lastsuckle.csv) lacks maternal ID and birth season variables, preventing certain longitudinal analyses.
• Column-level documentation is absent; field semantics must be fully inferred from the description.
