Imputed Definition & Meaning Dictionary.com

Imputation in genetics refers to the statistical inference of unobserved genotypes. It is achieved by using known haplotypes in a population, for instance from the HapMap or the 1000 Genomes Project in humans, thereby allowing to test for association between a trait of interest (e.g. a disease) and experimentally … Zobacz więcej In genetic epidemiology and quantitative genetics, researchers aim at identifying genomic locations where variation between individuals is associated with variation in traits of interest between individuals. Such studies hence … Zobacz więcej Designing accurate statistical models for genotype imputation is very much related to the problem of haplotype estimation ("phasing") and is an active area of research. Zobacz więcej • List of haplotype estimation and genotype imputation software • Haplotype estimation Zobacz więcej Genotyping arrays used for genome-wide association studies (GWAS) are based on tagging SNPs and therefore do not directly genotype all variation in the genome. Imputation of … Zobacz więcej There are several software packages available to impute genotypes from a genotyping array to reference panels, such as 1000 Genomes Project haplotypes.

Witryna12 paź 2015 · Imputation accuracy statistics can be classified into two types: (1) statistics that compare imputed to genotyped data and (2) statistics produced without reference to true genotypes. Concordance rate, squared correlation, and Imputation Quality Score (IQS) [ 13] are examples of the first type.
