Mission Statement
With the tremendous amount of resources devoted to collecting data, our mission is to transform numbers into meaningful information to help you to make decisions and optimize your strategic directions. Using a broad spectrum of statistical techniques, from the simple to the sophisticated, we create value through analysis.

  • Resources to estimate error bounds and assess statistical significance in transportation safety research
  • Comprehensive statistical analysis of large databases using sophisticated analysis tools for policy analysis and evaluation, including regression and logistic regression analysis
  • Technical report writing with evidence-based analysis
  • Short course development and delivery of statistical methods, especially manufacturing capability analysis, statistical process control and transportation safety research
