High-throughput biotechnologies, such as gene expression microarrays or mass- spectrometry-based proteomic assays, suffer from frequent missing values due to various …
Introduction The generic metabolomics data processing workflow is constructed with a serial set of processes including peak picking, quality assurance, normalisation, missing value …
OBJECTIVES: Missing data imputation is an important task in cases where it is crucial to use all available data and not discard records with missing values. This work evaluates the …
O Hrydziuszko, MR Viant - Metabolomics, 2012 - Springer
Missing values in mass spectrometry metabolomic datasets occur widely and can originate from a number of sources, including for both technical and biological reasons. Currently …
G Tutz, S Ramzan - Computational Statistics & Data Analysis, 2015 - Elsevier
Missing data raise problems in almost all fields of quantitative research. A useful nonparametric procedure is the nearest neighbor imputation method. Improved versions of …
P Jafari, F Azuaje - BMC Medical Informatics and Decision Making, 2006 - Springer
Background The analysis of large-scale gene expression data is a fundamental approach to functional genomics and the identification of potential drug targets. Results derived from …
Background Gene expression data frequently contain missing values, however, most down- stream analyses for microarray experiments require complete data. In the literature many …
We present a modification of the weighted K-nearest neighbours imputation method (KNNimpute) for missing values (MVs) estimation in microarray data based on the reuse of …
