| Abstract | Congress directed the Secretary of Transportation, through the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991, to carry out a study or studies to determine the impact of safety belt and motorcycle helmet use. In order to carry out the studies described in the Act, the National Highway Traffic Safety Administration (NHTSA) used the resources provided in the legislation to fund states to develop Crash Outcome Data Evaluation Systems (CODES). The states in the CODES project used a cost-efficient method (probabilistic linkage) of matching crash data to medical and insurance data. NHTSA wants to expand the establishment and use of these linked data sets. This report addresses logistic regression, a powerful statistical analysis, as a tool to use with the material in the CODES database. It allows researchers using qualitative measures of effectiveness, such as 'died versus survived,' to investigate relationships between that measure and many other measures simultaneously, whether those other measures are qualitative or quantitative. This document will introduce logistic regression to analysts who have limited experience or no experience with it. This paper is intended for users who have had course work in applied statistics at the college level or higher and who are familiar with the Chi-square test and linear regression. |
