Required Material:

(1) Student's background varies enormously for this class, and so will the level of book best suited to the student.
(2) We have one quarter whereas the books are intended for a full-year course.

I have recommended Hogg, McKean and Cragg, Introduction to Mathematical Statistics, Pearson.
Either the Seventh (2013) or the Eighth (2018) edition will do. They have exactly the same chapter and section numbering.
(My lecture notes are based on the seventh edition of this book).
A few days before classes start an electronic version (with try-before-you-buy access for 10 days) will be available through Red Shelf - click on the Modules tab in Canvas for access.
The electronic version for 180 days is $41.99 for the 7th edition and $86.99 for the eighth edition.

As this is available only for a limited time I would only do this if you also have another book.
The seventh edition will also be available for short-term loan at Shield Library Reserves.

For more advanced students a standard text is Casella and Berger (2002), Statistical Inference, Second Edition, Duxbury.
This is the most commonly-used text in Ph.D. economics courses but I think it is too advanced for most students (whereas Hogg et al. is viewed as the easiest of the graduate level texts).

For less prepared students, in particular for those who have not taken an undergraduate upper-division sequence in probability and statistics such as UCD's STA 130A-B or 131A-C you need to  have an undergraduate probability and statistics text that presents material more simply and with more examples. Old editions are fine and are cheap. Two such books are
Robert V. Hogg and Elliot Tannis, Probability and Statistics, Pearson.
Richard Larson and Morris Marx, Introduction to Mathematical Statistics and its Applications.

Because there is no perfect book and we have only one quarter to go through the essentials of both probability and statistics, I have made a complete set of slides for the course that will be posted on Canvas under Files / Typed lecture notes.

You still need a hardcopy text. This will be your reference book to go to when needed in subsequent classes and in research. And my lecture slides will have typos (still not completely cleaned up despite three years of teaching the material with three years of students having the opportunity to bring typos to my attention). The text books should be clean.

Computer Materials:

Assignments will include both theory and data examples using STATA.
STATA is available on both Econ and ARE computers, as well as some campus computers. it is used in subsequent econometrics classes.
For Economics students see for account on Painter.
For campus computers see virtual lab and 93 Hutchison and 2016 SciLab if available - see
If you choose to purchase Stata go to  The basic Stata/IC version is adequate.
To get started with Stata see

Course material will be posted at with slides, assignments, and past exams filed under Files. I will also post, after each class, a pdf of what I write during the class.

Academic Honesty: Academic dishonesty is unfair to the majority of students who are honest. To that end the Davis Division of the U.C. Faculty Senate has the following policies and asks that these be included in course syllabi.
(1) All undergraduate and graduate course outlines (syllabi) should list or provide a link to the U.C. Davis Code of Academic Conduct which is at . This provides many leading examples of academic misconduct. You should read this.
(2) One specific example of academic honesty is copying from solutions to assignments given in previous 239 courses.
(3) If an instructor has a reasonable suspicion of academic misconduct, whether admitted by the student or not, the instructor shall report the matter to the Office of Student Support and Judicial Affairs.
(4) The instructor has authority to determine a grade penalty when academic misconduct is admitted or is determined by adjudication to have occurred; with a maximum grade penalty of F for the course.

Out of class collaboration: You are allowed to work together in groups for the assignments, but each student must turn in an individual solution. Please indicate on the solution the names of the other students you worked with, if any that you worked with you on the problem set. it is not a violation of this policy to submit essentially the same answer on an assignment as another student, but it is a violation of this policy to submit a close to exact or exact copy.
