Imputation of missing values for compositional data using classical and robust methods
New imputation algorithms for estimating missing values in compositional data are introduced. A first proposal uses the k-nearest neighbor procedure based on the Aitchison distance, a distance measure especially designed for compositional data. It is important to adjust the estimated missing values to the overall size of the compositional parts of the neighbors. As a second proposal an iterativ...
متن کاملRobust Imputation of Missing Values in Compositional Data Using the -Package robCompositions
The aim of this contribution is to show how the R-package robCompositions can be applied to estimate missing values in compositional data. Two procedures are summarized, one of them being highly stable also in presence of outlying observations. Measures for information loss are presented, and it is demonstrated how they can be applied. Moreover, we introduce new diagnostic tools that are useful...
متن کاملMissing Values in a Relational Data Base
Although missing (or null) values are found in most data bases they are not formally recognized by existing DBMS. The correct manipulation of those values is then left to the applications programs. This paper extends and formalizes a model suggested by Codd (4) for the explicit recognition of missing values by the relational algebra. It also explores the implications of the model and discusses ...
متن کاملDealing with Missing Values in Data
Many existing industrial and research data sets contain missing values due to various reasons, such as manual data entry procedures, equipment errors and incorrect measurements. Problems associated with missing values are loss of efficiency, complications in handling and analyzing the data and bias resulting from differences between missing and complete data. The important factor for selection ...
متن کاملHandling Missing Values in Data Mining
Missing Values and its problems are very common in the data cleaning process. Several methods have been proposed so as to process missing data in datasets and avoid problems caused by it. This paper discusses various problems caused by missing values and different ways in which one can deal with them. Missing data is a familiar and unavoidable problem in large datasets and is widely discussed i...
