What SNP genotyping errors are most costly for genetic association studies?

Genetic epidemiology - 1 Feb 2004

Kang Sun Jung, Gordon Derek, Finch Stephen J

Abstract excerpt

Which genotype misclassification errors are most costly, in terms of increased sample size necessary (SSN) to maintain constant asymptotic power and significance level, when performing case/control studies of genetic association? We answer this question for single-nucleotide polymorphisms (SNPs), using the 2x3 chi(2) test of independence. Our strategy is to expand the noncentrality parameter of the asymptotic...
