Statistical data preparation: management of missing values and outliers
Missing values and outliers are frequently encountered while collecting data. The presence of missing values reduces the data available to be analyzed, compromising the statistical power of the study, and eventually the reliability of its results. In addition, it causes a significant bias in the results and degrades the efficiency of the data. Outliers significantly affect the process of estima...
متن کاملBayesian Clustering with Outliers and Missing Values
The Bayesian Robust Mixture Model (BRMM) is a fully probabilistic model for grouping realvalued data into a finite number of clusters. The model is robust in the sense that it tolerates outliers in the data and handles missing values, both within the Bayesian inference framework. Foreword The purpose of this report is to provide a detailed, step-by-step derivation of the variational update equa...
متن کاملMetabolomic Biomarker Identification in Presence of Outliers and Missing Values
Metabolomics is the sophisticated and high-throughput technology based on the entire set of metabolites which is known as the connector between genotypes and phenotypes. For any phenotypic changes, potential metabolite (biomarker) identification is very important because it provides diagnostic as well as prognostic markers and can help to develop new biomolecular therapy. Biomarker identificati...
متن کاملQuality of Geographic Data Detection of Outliers and Imputation of Missing Values Dissertation
i Abstract In Geographic Information System (GIS) typical applications data usually comes from a wide range of providers. Such data has variable quality and typically the end user has limited access to the original source (if any). Among other problems those datasets might have missing values and also be affected by outliers. Missing values are common in tabular datasets (like population census...
