Multivariate exploratory tools for microarray data analysis.

The ultimate success of microarray technology in basic and applied biological sciences depends critically on the development of statistical methods for gene expression data analysis. The most widely used tests for differential expression of genes are essentially univariate. Such tests disregard the multidimensional structure of microarray data. Multivariate methods are needed to utilize the inf...

Software Integration for Multivariate Exploratory Spatial Data Analysis

This paper describes a decade’s worth of evolution of integrating software to support exploratory spatial data analysis (ESDA) where there are multiple measured attributes. The multivariate graphics tools we use are XGobi, and more recently, GGobi. The paper is divided into two parts. In the first part, we review early experiments in software linking for ESDA, which used XGobi, different Geogra...

Graphical Methods for Exploratory Multivariate Longitudinal Data Analysis

This paper describes direct manipulation and dynamic graphics for analyzing multivariate longitudinal data. Longitudinal data measures individuals repeatedly in time, perhaps at irregular and unequal time points. There is an emphasis on studying the individual patterns as well as mean trends because we can. Static plots of individuals are messy and often unreadable because there are many overla...
