Witryna21 lut 2024 · Imputation is now an essential tool to improve the coverage and power of a genomewide association study (GWAS), facilitate downstream fine-mapping of a target region, and enable meta-analysis in consortiums when multiple datasets were genotyped on different array platforms[10]. Witryna4 lut 2024 · With this method imputations are implemented as part of the cross-validation procedure. Within each cross-validation fold, imputation is done once. By repeating this process over multiple imputation runs, multiply imputed training and test sets are generated. Model performance is evaluated and tested in the training and … Once you are happy with your input dataset, the most (computationally) efficient way to carry out imputation in large GWAS datasets is to use --greedy option and to carry out a two step process. The first step is to build a model that relates your samples to the haplotypes in the reference panel.
