Multivariate Data Visualization

Multivariate analysis deals with the statistical analysis of observations where there are multiple responses for each observational unit. Let X be an n μ p data matrix where the rows represent observations and the columns, variables. We will denote the variables by X1, X2, ..., Xp. In most cases it is necessary to sphere the data by subtracting out the means and dividing by the standard deviati...

Multivariate Lattice Models for Spatial Environmental Data

Environmental problems often include data that are not only spatial in nature, but also multidimensional with several measurements recorded at each spatial location. One example is the assessment of environmental equity. Figure 1 show maps of St. James Parish, Louisiana, with counts of whites and minorities for each of the twenty census block groups overlaid with the location of the facilities ...

Visualization of Multivariate Data Using Preattentive Processing

A new method for designing multivariate data visualization tools is presented. Multivariate data visualization involves representation of data elements with multiple dimensions in a low dimensional enviroment, such as a computer screen or printed media. Our tools are designed to allow users to perform simple tasks like estimation, target detection, and detection of data boundaries rapidly and a...
