Imputing ungenotyped markers
Witryna7 sty 2016 · Imputation of Ungenotyped Variants The motivation for using linear interpolation to impute ungenotyped variants is obtained from considering an HMM in which there is a HMM state for every reference marker. In this HMM, there are no observed data between genotyped markers in the imputation target. WitrynaImputation can be used for inferring genotypes at markers that have not been genotyped in one's sample. This is possible by using patterns of haplotypic variation seen in …

WitrynaWhen imputing missing ungenotyped markers with a reference panel, we average posterior genotype probabilities obtained from iterations R6. Our methods for haplotype-phase inference and genotype imputation are implemented in BEAGLE 3.0. BEAGLE produces most likely haplotypes and sampled haplotypes for each indi-vidual with all … Witrynabased on genotypes at typed markers and information about LD within the region [3,4,5,6,7,8,9,10,11,12]. These methods are particularly useful in the context of failed genotyping and combining data across multiple platforms and recently have been extended to untyped markers using a reference data set [8,10,11].
WitrynaWe investigate a Bayesian approach to modelling the statistical association between markers at multiple loci and multivariate quantitative traits. In particular, we describe the use of Bayesian Seemingly Unrelated Regressions (SUR) whereby genotypes at the different loci are allowed to have non-simu … Witryna15 kwi 2012 · There is therefore a need for imputation methods designed specifically for non-model organisms in which genomic resources are poorly developed and marker …
