publication Evidence: moderate

Author Information

Author(s): Ewens Warren J., Li Mingyao, Spielman Richard S.

Primary Institution: University of Pennsylvania

Hypothesis

What are the properties of the various Allison/Abecasis regression-based tests and the Rabinowitz and the Monks-Kaplan tests?

Conclusion

The review outlines the features and relationships of various quantitative transmission/disequilibrium tests used in genetic studies.

Supporting Evidence

  • The review discusses the properties of various quantitative TDT procedures.
  • It highlights the relationships between different testing procedures.
  • The review addresses power considerations in choosing the appropriate test.

Takeaway

This study looks at different tests that help scientists understand how genes might be linked to traits in families. It explains how these tests work and what they can tell us.

Methodology

The review discusses various quantitative TDT procedures and their properties, focusing on family trio data.

Potential Biases

The review notes potential issues with population stratification affecting regression-based tests.

Limitations

The review does not cover all quantitative TDT procedures and focuses only on family trios.

Participant Demographics

The study focuses on family trios, which consist of a mother, a father, and one child.
