Visual Pairwise Differences

This is a page under construction describes Inferential mark-up of plots to give approximate inferences for pair-wise differences.

The method is described in the following set of slides (pdf) used in talks in 2010 at ICOTS 8 in Slovenia in July, at the RSSCSE in Plymouth in October and in Chris Wild's keynote at the Australian Statistics Conference in Perth.

These methods are used in the iNZight system and have been in Census At School NZ's dataviewer (if you click "I am a year 12 student") since early 2009.

R code will be posted shortly
