The Department of Statistics is concerned with teaching, research, and statistical consulting. The courses offered present a comprehensive spectrum of statistical and probability theory, in so far as such theory is necessary for the un- derstanding and analysis of observational data. The applications of the theory delineated in the courses may be made in any field of experience. Laboratory classes in which examples related to the student’s actual field of interest are worked out, play an essential part. The department offers both B.A. and B.S. degrees in Statistics as well as a B.S. in Statistics with options in Statis- tical Computing and Quantitative Management; the M.S. degree in Statistics; and the Ph.D. degree in Applied Statistics.

The courses STAT 040, STAT 048, STAT 100A, STAT 100B, STAT 104/BUS 104, STAT 110, STAT 130, STAT 140, STAT 146, and STAT 155 are intended for students of other departments who wish a knowledge of statistical techniques. Some of them may be taken as electives by statistics majors. The objective of these courses is to acquaint the student with the elements of statistics with only the necessary amount of mathematical training.

STAT 147 and STAT 157 are computer-oriented courses intended for students who would like to learn about computer programming in the most important languages and who would like to learn about statistical computing.

Transfer Students Students transferring to the Statistics major must complete courses comparable to the following one-year sequence before they transfer:

• 1. First-year calculus, equivalent to MATH 007A or MATH 009A or MATH 09HA,

MATH 007B or MATH 009B or MATH 09HB, MATH 009C or MATH 09HC, each course completed with a grade of “B-” or better.

The department has two large undergraduate Windows-based teaching laboratories. These laboratories provide users access to a wide variety of statistical software packages including SAS, R, Minitab, and SPSS, and other popular software packages including Mathematica, Adobe Acrobat, and Microsoft Office. The department also houses the Garber Research Computing Laboratory, which is a combination of a UNIX/LINUX-based system with multiple workstations and several Windows-based machines.

The Statistical Consulting Collaboratory provides a broad range of analytical and statistical support services, including design of experi- ments, statistical inference, hypothesis testing, and data modeling for the campus community, and promotes cooperative research between statisticians and other investigators in all fields of the application of statistics. The Collaboratory is staffed by:

Yehua Li, Ph.D., Faculty Director and Karen Huaying Xu, Ph.D., Associate Director and rotating graduate students.

The Department of Statistics offers the M.S. degree in Statistics and the Ph.D. degree in Applied Statistics.

Admission Domestic and international applicants must supply scores from the GRE general exam. In addition, TOEFL scores must be supplied by applicants whose first language is not English who do not hold a degree from a U.S. institu- tion. The department considers applications for teaching assistantships at the same time as those for fellowships. Normally, Ph.D. eligible admitted students are awarded five year financial assistantship.

Master’s Program The Department of Statistics offers the M.S. degree in Statistics.

Admission Students entering the Master’s program must have completed a bachelor’s degree with sufficient training in Mathematics and a strong background in Statistics or have taken STAT 160A, STAT 160B, STAT 160C, STAT 161 and STAT 170A, STAT 170B, STAT 171, covering basic areas of probability and statistics.

Students must also meet the other requirements for admission as specified by the Graduate Division. The program is Plan II (Comprehensive Examination) described in the Graduate Studies section of this catalog. No foreign language is required.

Course Work Graduate students in Statistics must have taken appropriate courses in Mathematics to give them the proper background for graduate work in Statistics. Important areas include Calculus (at least MATH 009A, MATH 009B, MATH 009C, and MATH 010A) and Linear Algebra (at least MATH 131).

Degree Requirements Students are required to complete a minimum of 41 units that must include STAT 201A, 201B, 201C, STAT 202A, 202B, 202C, STAT 206, STAT 208, STAT 288, and two consecutive quarters of STAT 293.

Comprehensive Examination All M.S. students are required to take a written comprehensive examination and pass at the M.S. level, with no more than two attempts allowed to pass. The written qualifying exam is offered two times in each year, the first in Summer and the second in Fall quarter. All students in the program are required to take their first attempt of the exam in Summer. The second exam in Fall can only be taken by the students· who fail to pass the exam in their first attempt. Exceptions can be made based on the approval of Graduate Advisor. A program proposal is not required.

Advancement to Candidacy Advancing to candidacy takes place when stu- dents complete all the course requirements and pass the written exam. Professional Development Requirement: Two quarters of STAT 293 give students training in (a) the ability to use fundamental statistical techniques to formulate problem and solution in diverse real-world application; (b)the ability to use at least one statistical software package to conduct statistical data analysis; (c) the ability to communicate with researchers in statistical com- munity and other disciplines by using graphical methods to display and interpret information.

Petition to Change Degree Objective Some students can petition to change their degree objective from the M.S. degree to the Ph.D. program in Applied Statistics depending on their performances in the written comprehensive exam and coursework.

Doctoral Degree The Department of Statistics offers the Ph.D. degree in Applied Statistics.

The program emphasizes both the theory of statistics and its application to special fields of interest. In addition to courses in statistics, a student would take courses in a substantive field from which a thesis problem requiring a statistical approach should arise. The substan- tive field may be chosen from areas such as biology, economics, political science, psychology or administration. Specialties might include, for example, population genetics, biological control, hydrology, epidemiology, geology, discrimination in learning, or scales and measurements.

Admission Students entering the program must have completed either a bachelor’s degree or a Master’s degree in Statistics, Computer Science, Mathematics, or some other quantitatively based discipline. Students lacking sufficient prepara- tion for some statistics graduate classes must complete some preparatory work in Statistics, Computer Science, or Mathematics depending on their background. Students also have to meet the general requirements listed in the Graduate Studies section of this catalog.

Change Degree Objective Students with a Batchelor’s degree in the Ph.D. program who have satisfied all the requirements for the Master’s degree may apply for this de- gree while completing requirements for the Ph.D. program.

The written qualifying exam is offered two times in each year, the first in Summer quarter and the second in Fall quarter. Students who start coursework with STAT 210A take the first attempt at the written exam Summer quarter before the start of their second year. Students who start coursework with STAT 201A take the first attempt at the written exam in Summer quarter before the start of the third year. The second exam can only be taken by students who fail to pass the exam in their first attempt.
