SISG 2016 Modules

21st Summer Institute in Statistical Genetics

Module 7: Population Genetic Data Analysis

Week 2, Session 3, Monday 8:30 AM - Wednesday 12:00 PM: Mon Jul 18 to Wed Jul 20

This module serves as a foundation for many of the later modules.

A unified treatment for the analysis of discrete genetic data, starting with estimates and sample variances of allele frequencies to illustrate genetic vs statistical sampling and Bayesian approaches. A detailed look at Hardy-Weinberg and linkage disequilibrium, including the use of exact tests with mid-p-values and a new look at X-chromosome Hardy-Weinberg testing. A new characterization of population structure with F-statistics, based on allelic matching within and between populations with individual relationship estimation as a special case. Analyses illustrated with applications to forensic science and association mapping, with particular reference to rare variants. Concepts illustrated with R exercises.
