Multivariate Data Quality Enhancement by Ranked Imputation

2020 VOLUME-8 ISSUE-10, AUGUST 2019, REGULAR ISSUE  
This work presents a prediction-based data imputation technique, Rank Based Multivariate Imputation (RBMI) that operates on multivariate data.  ...  Real time data is prone to inconsistencies, which exhibit negative impacts on the quality of the predictions. This mandates the need for data imputation techniques.  ...  A data imputation model for genetic sequences was presented by Chen et al. [18] . The proposed Gimpute model creates pipelines to effectively perform imputation on genomes.  ...

Spatial constraints were linked to the genetic risk for schizophrenia and general cognitive functioning, thereby providing insights into their biological basis and behavioral relevance.  ...  Quality control and imputation was performed with Gimpute (31) (see Supplement for details).  ...  In addition, the genetic contributions to these phenotypes can be studied with modern genetic approaches utilizing the potential of cumulative genetic risk scores.  ...

Biologically informed risk scoring in schizophrenia based on genome-wide omics data

Junfang Chen
2020
For all given samples, standard quality control (QC) and imputation are performed using Gimpute pipeline ). The following QC steps were applied: 1.)  ...  The same genotyping QC and imputation procedure as above was applied for GWAS MGS data.  ...
