Resources
Good sources for data and information
- FRED - the database of the St. Louis Fed - extremely useful, fairly easy to use, highly recommended
- World dataBank - from
the World Bank, has annual data for 100s of variables from almost every
country on the planet, plus groups of countries. You pick your
countries, data series, and time periods, it'll create a downloadable
spreadsheet with your requested data. The only drawback is
there's a fair amount of missing data for some countries, some
variables, and some time periods.
- Gapminder World - the coolest way to visualize much of the data in the World dataBank
- Resources for Economists on the Internet (RFE) - click on "Data"
- Board of Governors of the Federal Reserve
- Economic Report of the President (ERP) - click on "statistical tables" for a list of the data
- Bilateral exchange rates
- you pick the country(ies) - you pick the dates - you pick the output
format and this site creates a table with your data
- Board
of Governors of the Federal Reserve System. Browse the horizontal
menu near the top of the page. Some useful places include the Beige Book, the Flow of Funds Accounts, and their Economic Research and Data page
Datasets used in class
Handouts and "virtual handouts"
- Here
is where I will post handouts I distribute in class and "virtual
handouts" for you to read on your computer or print out and add to your
notes.
- Applet: visualizing the least squares regression technique
- Worksheet: Probability and Statistics Review, used in class on 2/23, 2/25, and 2/28.
- Central Limit Theorem spreadsheet shown in class on 3/2 and 3/4. (warning: large file)
- Handout: Notes on Hypothesis Tests, version 3/8/2011
This
version corrects one substantive error in the version I distributed in
class Monday: in the very last sentence on p.7, the word
"largest" is incorrect and has been changed to "smallest."
Otherwise, this version contains minor edits and notes under the title
that the handout corresponds to Sections 3.2 through 3.5 of Chapter 3.
- Worksheet on hypothesis tests
- the first page is the worksheet we did in class, the second page is
the answer key with some notes about what we learn from this exercise.
- p-value calculator (Excel file)
- Study guide for Exam 1, version: 3/10/2011
- Handout on ESTTAB
- My old notes on confidence intervals, from my MBA stats class at UNLV, 4/11/2011
- Worksheet on confidence intervals, 4/11/2011
- Worksheet on Testing Joint Hypotheses with F tests, part 1 (includes answers) 4/18/2011
- Worksheet on Testing Joint Hypotheses with F tests, part 2 (includes answers) 4/18/2011
- Multicollinearity in Twenty Minutes, 5/2/2011
- Stata output - panel data estimation with the "guns" dataset, 5/9/2011
Stata resources
- UCLA: Resources to help you learn and use Stata
Some of the best ones here include: - Getting started with Stata resources from the Office of Population Research at Princeton University
- Introduction to Stata, by Christopher Baum - a longish PDF slideshow (though you can flip through the pages quickly) that highlights a lot of what Stata can do
- David Hummels' Stata Lectures
(they're more like learning modules). A few years old, and refer
to an earlier version of Stata, but still pretty good.
- Two-page Stata cheat-sheet, by Andy Grogan-Kaylor, University of Michigan
- A Brief Introduction to Stata with 50+ Basic Commands, by Tobias Pfaff, University of Münster, Germany. A 32-page introduction.
- Stata on a Mac, a blog by Adam Jacobs. For his tutorial entries, start under his December 2007 entries.
- Most of the above are from Stata's own "Stata resources" page. You might find some other good ones there, too.
Your midterm exams
- I will post your exams here, with an answer key, when they are ready.
- Exam 1 - the first half of the file is the actual exam you took; the second half is a detailed answer key.
- Exam 2 - the first half of the file is the actual exam you took; the second half is a detailed answer key.
Regression output for Exam 2
Old midterm exams
- Here
are the actual midterm exams (and answer keys) I used when I last
taught this course. Please be advised: the last time I
taught this course (Fall 2007), I was teaching at another school with
slightly longer semesters, and I used a different textbook. The
selection, order, and treatment of topics will surely be at least a
little different this semester. Therefore, it is not safe to assume
that the exams you take will look just like these exams, and you should
not over-rely on these old exams as you prepare for your exams.
Nonetheless, I think they might be useful, so I've posted them below.
- The final exam is not available. Don't ask for it.
- Old exam 1 (password protected - I'll give you the password in class)
- Old exam 2 (password protected)
