A Methodology for Analyzing General Categorical Data with Misclassification Errors with an Application in Studying Seat Belt Effectiveness.

摘要

A methodology for analyzing general categorical data with misclassification errors is developed and applied to the study of seat belt effectiveness. For the study of belt effectiveness,the original sample is drawn from North Carolina accident reports for the first eight months of 1975. Chapter I presents some background material,while Chapter II outlines the mathematical derivation of the proposed methodology. (Details of the statistical methodology are given in Appendix A). In Chapter III,the data to which the methodology is applied in examining safety belt effectiveness is described. Results of the investigation are given in Chapter IV. An examination of the nature and magnitude of misclassification errors in this police-reported belt and injury data is described in Chapter V. A brief discussion of this work along with suggestions for futher research are included in Chapter VI.
