Services Offered:
Data visualization
- Map design, including choices of color scheme and representation method for the data and its reliability.
- Graph design that highlights the important features in your data and clearly communicates your message to the target audience.
- Design of graphics that link data features with geographic variation, such as by linked micromaps.
Spatial statistical analysis
- Application of statistical regression models that incorporate spatial variability to identify important predictors of your outcome, and that can identify regions or subgroups of people with an unusually high or low rate or number of events.
Examples:
-
estimation of the number of new cancer cases that will occur in the upcoming year for the American Cancer Society's Cancer Facts & Figures, the most cited cancer reference in the world; the model estimated casecounts for states with missing data, then projected ahead 4 years from available data to the current year (Pickle, Hao, Jemal et al. in CA: A Cancer Journal for Clinicians, 2007).
-
identification of breast cancer tumor and patient characteristics, including distance from residence to nearest mammography facility, that explained local geographic variation of late stage disease within Los Angeles county (Gumpertz, Pickle, Miller, Bell in Cancer Causes & Control 17:325-339, 2006).
-
identification of individual and community level associations with mammography use in Los Angeles county; results included an association with a greater density of mammography facilities and identification of high mammography use among Latina women with limited English proficiency, a group that had been targeted for outreach in LA (Meersman, Breen, Pickle, Meissner, Simon in Cancer Causes & Control 20(8):1469-82, 2009).
-
analysis of associations between characteristics of residents, their neighborhoods and roadways and the likelihood that people walked or rode a bike as a means of transportation; results showed that even after controlling for personal characteristics, the roadway characteristics were significantly related to walking/biking more often and for longer duration (Berrigan, Pickle, Dill in Int Journal of Health Geographics 2010)
- In the future, services will be expanded to include analysis of computer networks, both architecture of new systems and performance evaluation of existing ones.
