The Grand Tour as a Method for Detecting Multivariate Outliers

A method of viewing multivariate data vectors and identifying among them outliers is described. The method is applied to two sets of benchmark data: Brownee's stack-loss data and Hawkins{Bradu{Kass data. All the outliers contained in these data are easily identiied. Generally, it is expected that the method will yield good results (i.e. will nd the outliers) for data having elliptical or nearly...

A new method for detecting outliers in Data Envelopment Analysis

We introduce a simple method for detecting outliers in Data Envelopment Analysis. The method is based on two scalar measures. The first is the relative frequency with which an observation appears in the construction of the frontier when testing the efficiency of other observations, and the second is the cumulative weight of an observation in the construction of the frontier. We provide a link t...

A Graphical Method of Detecting Pneumonia Using Chest Radiograph

An important ingredient of health care is the correct initial diagnosis of chest ailments using images of chest radiograph. This paper develops a simple graphical method to aid the initial screening and discrimination of pneumonia patients (PNEU) from pulmonary tuberculosis (PTB) patients, lung cancer (LC) patients and normal healthy individuals (NL). Approximate confidence regions using princi...

Detecting Outliers in Exponentiated Pareto Distribution

In this paper, we use two statistics for detecting outliers in exponentiated Paretodistribution. These statistics are the extension of the statistics for detecting outliers inexponential and gamma distributions. In fact, we compare the power of our test statisticsbased on the simulation study and identify the better test statistic for detecting outliers inexponentiated Pareto distribution. At t...

On Detecting Spatial Outliers

The ever-increasing volume of spatial data has greatly challenged our ability to extract useful but implicit knowledge from them. As an important branch of spatial data mining, spatial outlier detection aims to discover the objects whose non-spatial attribute values are significantly different from the values of their spatial neighbors. These objects, called spatial outliers, may reveal importa...
