Finding an unknown number of multivariate outliers
We use the forward search to provide robust Mahalanobis distances to detect the presence of outliers in a sample of multivariate normal data. Theoretical results on order statistics and on estimation in truncated samples provide the distribution of our test statistic. We also introduce several new robust distances with associated distributional results. Comparisons of our procedure with tests u...
متن کاملFinding Multivariate Outliers by Dynamic Graphics
AMS91 classiication: 62-07, 62-09, 68U05 We present shortly the most important methods used for detecting multivariate outliers, among them the recently developed grand tour method based on dynamic graphics. The advantage of the graphical approach is stressed. An example { the bushhre data { is analyzed using some sequentially trimmed Mahalanobis distances and the grand tour. The last approach ...
متن کاملFinding multivariate outliers in fMRI time-series data
A fundamental challenge for researchers studying the brain is to explain how distributed patterns of brain activity relate to a specific representation or computation. Multivariate techniques are therefore becoming increasingly popular for pattern localization of functional magnetic resonance imaging (fMRI) data. The increased power of these techniques can be offset by their susceptibility to m...
متن کاملIdentification of local multivariate outliers
Abstract The Mahalanobis distance between pairs of multivariate observations is used as a measure of similarity between the observations. The theoretical distribution is derived, and the result is used for judging on the degree of isolation of an observation. In case of spatially dependent data where spatial coordinates are available, different exploratory tools are introduced for studying the ...
متن کاملFinding outliers at multiple scales
Outlier detection targets those exceptional data whose pattern is rare and lie in low density regions. In this paper, under the assumption of complete spatial randomness inside clusters, we propose an MDV (Multi-scale Deviation of the Volume) approach to identifying outliers. In addition to assigning an outlier score for each object, it directly outputs a crisp outlier set. It also offers a plo...
