Abstract

In this talk, we will demonstrate how statistical graphics and visual data mining can be applied to a variety of biostatistical research projects. First, we will see how various graphical methods can be used for the simultaneous exploration of cgh and gene expression arrays. Next, we will demonstrate how graphics can be used to further assess numerical results in the context of expert raters' agreement for diagnosing carpal tunnel syndrome. Finally, we will show how so-called micromaps can be used to visualize the spred of the West Nile Virus and the occurrence of oral clefts across the United States. We will finish with a brief outlook on planned future research on graphical work in the framework of functional activity data in sleep medicine. In conclusion - while statistical graphics is a discipline by itself - there is a huge potential for statistical graphics in the context of biostatistical research.
