متن کاملChoosing Color Palettes for Statistical Graphics
Statistical graphics are often augmented by the use of color coding information contained in some variable. When this involves the shading of areas (and not only points or lines)— e.g., as in bar plots, pie charts, mosaic displays or heatmaps—it is important that the colors are perceptually based and do not introduce optical illusions or systematic bias. Here, we discuss how the perceptually-ba...
متن کاملTarget practice : choosing target conditions for test
Test accuracy varies depending on how the presence of disease is defined. For example, the sensitivity of computed tomographic (CT) colonography to detect colorectal neoplasia has been estimated at 96% for detecting invasive cancer, 86% for medium to large polyps, but as low as 45% when polyps of all sizes are included in the definition of disease. To interpret these results, we need to decide ...
متن کاملChoosing a Test Modeling Language: A Survey
Deployment of model-based testing involves many difficulties that have slowed down its industrial adoption. The leap from traditional scripted testing to model-based testing seems as hard as moving from manual to automatic test execution. Two key factors in the deployment are the language used to define the test models, and the language used for defining the test objectives. Based on our experi...
متن کاملA statistical test for outlier identification in data envelopment analysis
In the use of peer group data to assess individual, typical or best practice performance, the effective detection of outliers is critical for achieving useful results. In these ‘‘deterministic’’ frontier models, statistical theory is now mostly available. This paper deals with the statistical pared sample method and its capability of detecting outliers in data envelopment analysis. In the prese...
