RTP expanded and prospered after its inception, so did RTI. Growing
from a handful of scientists in central North Carolina in 1959 to a
staff of more than 2800 in more than 40 countries today, RTI is now one
of the world’s leading independent, nonprofit research and development
Our activities both mirror and support national priorities and policies
as well as diverse commercial, industrial, and academic endeavors. For
instance, as public and government interest in environmental protection
grew in the 1960s, so did related programs at RTI, building on our
expertise in statistical, physical, and life sciences.
Environmental modeling allows scientists to examine details of the natural environment in ways that we can’t in the real world. Physical, mathematical, or numerical approximations allow us to better understand existing processes and interactions and to estimate what-if scenarios, such as the emission, transport, and effects of pollution.
Researchers use comprehensive and well-structured data sets, models that describe physicochemical processes or implement decision methodologies, and data analysis and visualization tools to reveal and present new insights from environmental research studies. Our state-of-the-art information technology capabilities facilitate our advanced environmental research activities. Key areas include information system design and implementation, geospatial analysis and applications development using geographic information systems (GIS), with associated management of environmental data sets.
RTI International is a world class provider of information technology (IT) services, supporting the initiatives of state and federal governments as well as private sector clients. With over 200 computing professionals in our organization, RTI designs, develops, builds, tests, and deploys information management systems and IT infrastructures.
SUDAAN is a software product designed and developed by RTI statisticians for analyzing clustered data arising in many applications, including complex sample surveys, randomized experiments, and epidemiological studies. SUDAAN offers procedures for descriptive statistics and for statistical modeling. The modeling procedures include both linear and multinomial-logistic models and a procedure for fitting proportional hazards (Cox) regression models for time-to-event data.
