I have posted general information on the final examination (PDF file). You are expected to download FinalData.dat (FinalData.dat.txt) containing two data sets to be analyzed prior to the in-class examination on December 21.

I have posted a slightly modified version of this which clarifies how the meat samples were selected.

Errors in Textbook

There are some errors in Oehlert's text. Some of them have been collected in a PDF file. In particular this contains a correction to the sums of squares provided in Exercise 10.1.

Frequently Asked Computing Questions

I have posted a web page for Frequently Asked Computing Questions. I expect many of these will concern MacAnova, but other issues may come up.

Topics as of 10/6/02

• Accessing Acrobat PDF Files (9/7/02)
• Printing neat ANOVA tables (10/1/02)
• Why am I getting an error message when I use contrast()? (10/1/02)
• Plots to diagnose non-constant standard deviation
• What does boxcox() do? (10/1/02)
• What are Cook's D, HII and rankits? (10/1/02)
• How can I compute the power of a test of a contrast? (10/3/02)
• Choice of weights to define a contrast that involves more than 2 treatments (10/3/02)
• Query on Exercise 6.6 (10/6/02)
• Query on Ex. 7.5 (10/8/02)
• Is there a easy way to identify the most extreme outliers? (10/28/02)
• How can I create factors for treatments in standard order? (11/08/02)

MacAnova Macros

I will post here any new MacAnova macros you may find useful.

• File type2anova.mac (or type2anova.mac.txt) contains macro type2anova(). It computes ANOVA tables with Type II SS (revised version posted 8:00 11/4/02).
  Typical usage:
  
  Cmd> type2anova("y=a*b*c",fstat:T)
  
  In place of "y=a*b*c" you can use any ANOVA model as long as it has no "aliased" columns (missing degrees of freedom).

Before using a macro file, you should run the following command:

Cmd> addmacrofile(getfilename())

This will bring up a file navigation dialog box. You should find the macro file and select it and click on Open or OK. Then you can use any macro in the file normally.

Class notes and overheads

Within a few days after most lectures, I will post on the web edited copies of the overheads used. You can download them from http://www.stat.umn.edu/~kb/classes/5303/classnotes.html. You will need the special user name and password announced in class to access them.

Please let me know if you have any problem reading them. You will need a special user name and password provided in class to access them.

Data Files

Oehlert data sets
All of the data used in the text is available in computer readable form. You can download data in several forms from http://www.stat.umn.edu/~kb/5303/oehlertdatafiles.html. If you have your own computer, you will probably find it convenient to download a complete set of files to keep on your hard drive. They will all fit on a single 1.44M floppy disk.
