RESEARCH TRIANGLE PARK, N.C. — Leading statisticians from RTI International will present new research related to statistical methodology at the annual American Statistical Association's Joint Statistical Meetings, July 28 - August 2 in San Diego, Calif.

The conference is the world's largest gathering of statisticians, bringing together more than 6,000 attendees. The theme of this year’s conference is “Statistics: Growing to Serve a Data-Dependent Society.”

RTI researchers will present 20 papers and poster presentations that highlight the institute’s efforts to inform sound public policy through the use of objective, independent statistical analysis.

RTI will also be showcasing the newly released SUDAAN® 11 statistical software package at the conference. Developed by researchers at RTI, SUDAAN provides descriptive and modeling procedures for analyzing survey and other cluster-correlated data encountered in epidemiological studies, clinical trials, experimental studies and longitudinal studies. The newest version of the software is 50 percent larger than the previous release and offers several enhancements based on customers' needs, requests and feedback.

RTI presentations at the conference will include:

  • ABS and Cell Phones: Appending Both Cell Phone and Landline Phone Numbers to an Address-Based Sampling Frame
