Genome-Wide Association Data: Where Are the Standards? (Chapter 2)
In this chapter we assess the predictive strength of a number of classical statistical methods by applying them to a publically available set of amyotrophic lateral sclerosis (ALS) data reported in a paper by Schymick and colleagues (2007).1 We used these methods in the context of a single locus genome wide association study (GWAS) experiment. The methods are compared and the degree of similarity/dissimilarity between them is empirically measured to determine if a combination of methods is more predictive of phenotype genotype associations than a single method. All of the methods in our assessment are single nucleotide polymorphism (SNP) based.
