PIPs for 18 POPs and log-LTL from NHANES 2001-2002

Posterior inclusion probabilities (PIPs) for 18 persistent organic pollutants (POPs) and log-transformed leukocyte telomere length (log-LTL) derived from the NHANES 2001-2002 survey. Kaizong Ye generated this 9.5 KB dataset using component-wise and hierarchical variable selection for modified BART and BKMR models. The data is stored in an XLS file and was last updated on May 11, 2026.

Use Cases

• Compare variable selection performance between component-wise and hierarchical methods based on the described PIPs.
• Benchmark modified BART and BKMR models using the provided posterior inclusion probabilities for 18 POPs.
• Investigate associations between environmental chemical mixtures and a biomarker of aging (log-LTL) based on the NHANES-derived data.

Strengths

• Data is derived from the authoritative NHANES 2001-2002 survey.
• File size is 9.5 KB, indicating a focused and easily shareable dataset.
• Results are provided for two distinct variable selection methods (component-wise and hierarchical).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is limited to a single survey cycle (2001-2002).
