Masqueraders in computer intrusion detection are people who use somebody else's computer account. We investigate a number of statistical approaches for detecting masqueraders. To evaluate them, weâ€¦ (More)

We consider visual methods based on mosaic plots for interpreting and modeling categorical data. Categorical data are most often modeled using loglinear models. For certain loglinear models, mosaicâ€¦ (More)

Unlike other electrophysiological measurements such as electrocardiography (ECG) and electroencephalography (EEG), the cutaneous measurement of the electrical activity of the stomachâ€¦ (More)

This paper describes the integration of interactive statistical graphics within R using state-of-the art R-connectivity. The iPlots project uses SJava to deliver interactive plots for R and anâ€¦ (More)

Dealing with missing values is inconvenient in many ways. Although every statistician has to admit that the structure of missing values can be very meaningful for the interpretation of data, neitherâ€¦ (More)
