About the Cover
The cover image is by artist Joella Jean Mahoney, who paints striking abstract
landscapes inspired by the American Southwest. In her work, Mahoney is able to
beautifully capture the underlying structure of rock formations and canyons. In
statistical analyses, we work to capture and learn from the underlying structure we
find in data. While the images we create are not nearly as beautiful as Mahoney’s
work, in this sense we share a similar goal!
