News for 90-776
4/22/1999 New due date for your projects: May 7th
4/22/1999 Class on Monday, April 26, will held in a computer lab - room A003. Gary will teach you all about how to run SAS programs in UNIX, and you will be able to follow along at a computer. Wednesday's lab (April 28) will be time for you to finish up your projects.
4/14/1999: Lab 5, part 9. Please take a smaller sample than 15% if you are having space problems
4/6/1999: Extra office hours! From this Sunday until the end of the month, there will be an additional session of office hours on Sunday afternoons from 2-4 in A100.
4/1/1999: There are a couple of corrections for homework assignment 3, problem 2.
First, please skip problem 2, part e. It turns out that there are no missing values. This means that parts f and g should now refer to the data set you created in part d.
Second, for part h (problem 2), you will get pages and pages of output. To avoid this, please make the following additions to your MEANS procedure:
a) Only print out the MEAN statistic (no min, max, etc.)
b) Only print out the means for 2 variables : mean employment and mean number of establishments
c) Only calculate the means for the 2 digit SICs from 70 to 89. (Use the WHERE subcommand.) These are the service sector industries. For more information about what the 2 digit Standard Industrial Classification codes are, see http://www.census.gov/epcd/naics/nsic2ndx.htm#S0
d) One way to see more easily if there are any trends across time is to repeat your MEANS procedure by year, rather than by industry and year.
3/23/1999: Homework 2, problem 2, second to last sentence should read:
"For the SEEDED variable, you will need to create a value format."
3/23/1999: Homework 2, problem 2. In your codebook, you should include the number of observations in the data set. It is a good practice to report the number of observations for each variable.
3/15/1999: If you were not in class today (and you plan on taking the class), please let me know. Please also indicate whether you are registered for the class or if you are on the wait list. If you are on the wait list, I will arrange to have you officially registered.
3/15/1999: I lied - it turns out that I will be around on Tuesday (3/16), so feel free to bug me if you need to.
