Economics 1A-B, Statistics 13 or 32 and Math 16A-B or consent of instructor.
The essential prerequisites are exposure to introductory lower-division courses in economics and statistics.
Relationship to Economics 140
Economics 140 (Econometrics) is a more advanced course that also covers the methods of Economics 102.
Economics 140 has Economics 102 or Statistics 108 as a prerequisite.
For more on possible data classes see http://cameron.econ.ucdavis.edu/e102/morestat.html
Topical Outline by Lecture Number:
The text is A. Colin Cameron, Analysis of Economics Data: An
Introduction to Econometrics.
The first four chapters are posted on Canvas / Files and the remainder will be made available later.
For all topics an essential ingredient is that economics data be analyzed throughout. This includes some case studies.
For some chapters we will not cover the entire chapter. The key sections will be announced as we go along.
A. UNIVARIATE: Analysis of a single economics variable
Lecture 1: Introduction and getting going on Stata (chapter 1 + Stata http://cameron.econ.ucdavis.edu/stata/stata.html).
Lecture 2: Summarizing data using descriptive statistics and visualizing data using charts (chapter 2)
Lecture 3: The sample mean (chapter 3, appendix A)
Lecture 4: Statistical inference based on the sample mean using estimation and confidence intervals (chapter 4.1-4.3)
Lecture 5: Statistical inference based on the sample mean using hypothesis tests (chapter 4.4-4.7)
B. BIVARIATE REGRESSION: The relationship between two
Lecture 6: Bivariate data summary: scatter plots,
correlation and regression (chapter 5.1-5.5)
Lecture 7: ***** First midterm exam *****
Lecture 8: Bivariate data summary: regression, goodness of fit (chapter 5.5-5.12)
Lecture 9: The least squares estimator (chapter 6)
Lecture 10: Statistical inference on regression coefficients (chapter 7)
Lecture 11: Bivariate case studies (chapter 8)
Lecture 12: Models with natural logarithms (chapter 9)
Lecture 13: ***** Second midterm exam *****
A. Colin Cameron, Analysis of Economics Data: An Introduction
Relevant chapters will be posted at the Canvas course site.
The datasets and Stata programs used in the course notes are at http://cameron.econ.ucdavis.edu/aed/
The course Canvas site has assignments.
The website http://cameron.econ.ucdavis.edu/e102/e102.html has past exams and solutions and some links to Stata material.
There are usually free tutors for 102: see http://economics.ucdavis.edu/undergrad-program/tutoring
The Khan Academy has excellent video tutorials and exercises. See https://www.khanacademy.org/math/ap-statistics
|A. Univariate||Chapters 1-4, Appendix B
|B. Bivariate Regression
|C. Multiple Regression||Chapters 10-11, 14-16
These are held in a university computer lab in Hutchison 93.
Computer Materials: Assignments use Stata.
Stata is installed in 93 Hutchison, 2101 SCC, and the Virtual Lab (after 2060 SciLab closes - see https://virtuallab.ucdavis.edu)
To see whether 93 Hutchison and 2101 SCC are available see https://computerrooms.ucdavis.edu/available/.
If you choose to purchase Stata go to https://www.stata.com/order/new/edu/gradplans/student-pricing/
Stata/BE is more than adequate and costs $48 (6 months), $94 (1 year); $225 (permanent copy). Note that ECN140 and some other courses such as ECN 132 also use Stata.
Older versions of Stata are fine.
To install Stata after it is
purchased: (1) Choose the correct operating system (e.g.
Windows or Mac); (2) Choose the correct version of Stata - the
student price version is Stata/IC; (3) When you first run
Stata after installation it will ask for an "authorization
code". These codes are given in a pdf attachment you will
received in the email from Stata following purchase (some are
lengthy and it is easiest to cut and paste them in).
20% Due 10.00 a.m.
Fridays October 1; October

Midterm Exam1: 20% Thursday October 14
Midterm Exam2: 20% Thursday November 4
Final Exam: 40% Monday December 6 10.30 a.m.- 12.30 p.m. Comprehensive (about half on material up to 2nd midterm and about half the remainder).
Bring SCANTRON for exams.
Assignments: are posted on Canvas under Files / Homeworks. My solutions will also be posted there.
Assignments solutions by you are to be posted (as a pdf) on Canvas under Files / Assignments.
Assignments will generally be graded satisfactory (4 points) or unsatisfactory (0 points); very occasionally partial credit will be given.
Academic honesty is required - see below.Exams are closed book with a mixture of short answer (about two-thirds) and multiple choice (about one-third) questions.
