We present CAREY, an alert system notification for regions in state of emergency. CAREY implements the mediator-wrapper architecture on top of the Geospatial Web to visualize risky regions in terms of their weather conditions. We illustrate the formalization of the problem of detecting risky regions as a two-fold problem that relies on annotations of sensor data with the ontology of Observation...

Collecting and analyzing data lies at the basis of the scientific method: findings about nature usher new ideas, and experimental results support or refute theories. All this is not very prevalent in computer science, possibly due to the fact that computer systems are man made, and not perceived as a natural phenomenon. But computer systems and their interactions with their users are actually c...

Data on 17348 weaning weight records from a beef cattle crossbreeding operation were used to determine the effect of outliers on regression coefficients. Different criteria were used for detecting potential influential points. Eliminating a small number (932 or 5.4%) influential points resulted in the improvement of the model fitted. The R values increased from 41% to 49% while the mean square ...

In this article we extend and implement the forward search algorithm for identifying atypical subjects/observations in factor analysis models. The forward search has been mainly developed for detecting aberrant observations in regression models ( Atkinson, 1994 ) and in multivariate methods such as cluster and discriminant analysis ( Atkinson, Riani, & Cerioli, 2004 ). Three data sets and a sim...

The detection of influential observations for the standard least squares regression model is a question that has been extensively studied. LAD regression diagnostics offers alternative approaches whose main feature is the robustness. In this paper a new approach for nonparametric detection of influencial observations in LAD regression models is presented and compared with other classical method...

more than five hundred chemically injured patients were admitted to the labbafi-nejad medical center in spring of 1984. these patients were of two groups. the majority of patients had extensive skin burns, eye injuries as well as respiratory problems, and a second group of patients suffered mainly from neuromuscular and psychological problems. in this report, clinical manifestation and observat...

Pre-test estimator has been studied to estimate the mean of a normal distribution when non-sample prior information is avaliable. Our aim is to consider pre-test estimator of the mean in thepresence of outliers. A well known procedure to define pre-test estimator of the mean is using thesample mean. However, the sample mean is not a robust location parameter. In order to overcom...

So far we do not have much serious scholarship on the study of polygamy in ancient China, except for collections of literary compositions. Keith McMahon's newest book, Women Shall Not Rule: Imperial Wives and Concubines in China from Han to Liao, fills in this blank in the field of Chinese studies. In this book, written with conscientiousness and compassion, Keith McMahon illustrates early Chin...
