SNP Selection and Multidimensional Scaling to Quantify Population Structure

GENETIC EPIDEMIOLOGY, 33(6), 488–496.

By: K. Miclaus n, R. Wolfinger* & W. Czika*

author keywords: population stratification; substructure-informative SNP selection; Hardy-Weinberg disequilibrium; nonmetric MDS; association studies
MeSH headings : Algorithms; Genetic Markers; Genetics, Population / methods; Genome-Wide Association Study; Humans; Polymorphism, Single Nucleotide; Selection, Genetic
TL;DR: This work develops methodology for single nucleotide polymorphism (SNP) selection and subsequent population stratification visualization based on deviation from Hardy‐Weinberg equilibrium in conjunction with non‐metric multidimensional scaling (MDS); a distance‐based multivariate technique.

2004 journal article

Properties of the multiallelic trend test

BIOMETRICS, 60(1), 69–74.

By: W. Czika* & B. Weir n

author keywords: case-control test; multiallelic markers; nongametic linkage disequilibrium
MeSH headings : Alleles; Biometry; Case-Control Studies; Chi-Square Distribution; Genetic Markers; Humans; Linkage Disequilibrium; Models, Genetic
TL;DR: It is shown here that the multiple‐allele version of Armitage's trend test has increased power over the two‐alleel version under the requirement of equifrequent alleles, but not in general. (via Semantic Scholar)
