Material for Preliminary Exam B --- Statistics Section

The following list gives topics on which the Preliminary Examination B in Statistics will be based. STATS 5312 and 5313 (MATH 5312-13) cover many, but not necessarily all, of these topics. Students (even those who have taken STATS 5312-13) are advised to prepare for the examination using many resources, including (but not limited to) the books suggested below.
