Abstract:
|
The research team at SPSS has developed an engine for the production of statistical graphics based on the principles of Wilkinson's The Grammar of Graphics. This engine, together with the specification language used to define graphics, has proved capable of producing virtually any manner of statistical graphic and also a comprehensive subset of visualizations invented in other fields. In this presentation, we will show how we have applied Grammatical principles to the visualization of statistical models, as opposed to statistical data. We will give examples of several types of statistical model and will also show an example of the visualization of a distributed model; that is, a statistical model calculated on a grid of 256 computers, each with a partition of the overall data set of one billion rows.
