Genotype Imputation from Large Reference Panels

Witryna22 wrz 2024 · The imputation procedure is usually divided into two steps: First, given genotype data without haplotypic information, the data needs to be phased first to deduce haplotypes. These estimated haplotyes are then used in the second step to impute missing genotypes.
