Investigating Data With Andrews Plots
Most data that are collected are multivariate in nature, and much of them can be regarded as continuous. In the initial stages of analysis, graphic displays can be used to explore the data, but for multivariate data, traditional histograms or twoor three-dimensional scatter plots may miss complex relationships that exist in the data set. A number of methods for graphically displaying multivaria...
متن کاملVisualizing Independence Using Extended Association Plots
Association plots—a visualization technique for the independence problem in 2-way contingency tables—are extended in three directions: 1. The visualization is enhanced by using colors for the importance of the residuals. 2. The implementation currently available in R is improved using a more modular design and allowing a more flexible specification of plotting parameters. 3. Two methods for the...
متن کاملEnvelope plots of ordered Mahalanobis distances: uses and efficient generation
Systematic departures from a reference sampling scheme, such as multivariate normality, can affect all the observed ordered Mahalanobis distances (OMDs) – not just a few extreme values – causing distinctive changes to their overall pattern. Envelope OMD plots provide a useful framework against which to ‘read’ such changes, often suggestive of further, confirmatory analyses. Illustrative example...
متن کاملVolcano plots in hydrogen electrocatalysis – uses and abuses
Sabatier's principle suggests, that for hydrogen evolution a plot of the rate constant versus the hydrogen adsorption energy should result in a volcano, and several such plots have been presented in the literature. A thorough examination of the data shows, that there is no volcano once the oxide-covered metals are left out. We examine the factors that govern the reaction rate in the light of ou...
متن کاملVisualizing Independence Using Extended Association and Mosaic Plots
Two visualization techniques for the independence problem in 2-way contingency tables—assocation and mosaic plots—are extended in two directions: 1. The visualization is enhanced by displaying the significance of an appropriate test for independence and by using improved color schemes. 2. The implementation in the R system is improved using a more modular design and allowing for more flexible s...
