Exploring Cook's Statistic Graphically

The American Statistician, 1995
Abstract An index plot of Cook's statistic is frequently used to highlight influential observations. In this article we illustrate how enhanced higher dimensional plots of Cook's statistic can provide further useful information about sets of influential observations. We provide examples using normal and generalized linear models.

Statistics and Graphics Online

2018
In the chapter are indicated the main links of the isotopies between the static information and the different ways of graphic representation for the readers of online newspapers. Besides, a set of examples of news is presented with statistic data, analyzing those that boost or discourage iconicity and the ease of understanding. Finally, a study is made

Programming statistical graphics

2007
Users of statistical computing need to produce graphs of their data and the results of their computations. In this chapter we start with a general overview of how this is done in R, and learn how to draw some basic plots. We then discuss some of the issues involved in choosing a style of plot to draw: it is not always an easy choice, and there are ...

Research in Statistical Graphics

Journal of the American Statistical Association, 1987
Abstract Three active areas of research in statistical graphics are methodology, computing, and graphical perception. The five articles in this special section provide a good representation of these areas. Dynamic graphical methods, which involve a tight weaving of methodological and computing issues, are a particularly exciting topic of research ...

Animated Transitions in Statistical Data Graphics

IEEE Transactions on Visualization and Computer Graphics, 2007
In this paper we investigate the effectiveness of animated transitions between common statistical data graphics such as bar charts, pie charts, and scatter plots. We extend theoretical models of data graphics to include such transitions, introducing a taxonomy of transition types. We then propose design principles for creating effective transitions and

A graphical calculator for statistical analysis

Journal of the American Pharmaceutical Association (Scientific ed.), 1947
Abstract The graphical calculator originally developed for calculating penicillin concentrations from zone diameters in the three‐hour cylinder‐plate assay is shown to possess properties that recommend it for statistical analysis. By the introduction of two additional scales, the instrument is fitted to test data for deviation from normal distribution

Statistical Graphics: Mapping the Pathways of Science

Annual Review of Psychology, 2000
▪ Abstract  This chapter traces the evolution of statistical graphics starting with its departure from the common noun structure of Cartesian determinism, through William Playfair's revolutionary grammatical shift to graphs as proper nouns, and alights on the modern conception of graph as an active participant in the scientific process of discovery ...

Descriptive statistics and graphics

2008
Before going into the actual statistical modelling and analysis of a data set, it is often useful to make some simple characterizations of the data in terms of summary statistics and graphics.

Describing Data: Statistical and Graphical Methods

Radiology, 2002
An important step in any analysis is to describe the data by using descriptive and graphic methods. The author provides an approach to the most commonly used numeric and graphic methods for describing data. Methods are presented for summarizing data numerically, including presentation of data in tables and calculation of statistics for central tendency,

Census Bureau Statistical Graphics

1981
For some time, the U. S. Bureau of the Census has published statistical data in graphical as well as tabular formats. These graphical displays include barcharts, piecharts, line graphs, time series plots and univariate and bivariate statistical maps. Such publication graphics are provided both monochromaticaly and in color.
