Errors in Textbook
There are some errors in Oehlert's text. Some of them have beencollected in a PDFfile. In particular this contains a correction to the sums ofsquares provided in Exercise 10.1.
Frequently Asked Computing Questions
I have posted a web page for FrequentlyAsked Computing Questions. I expect many of these will concernMacAnova, 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)
- 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:
This will bring up a file navigation dialog box. You should find themacro file and select it and click on Open or OK. Then you can use anymacro 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 toaccess them.
Please let me know if you have any problem reading them. You willneed a special user name and password provided in class to accessthem.
Data Files
Oehlert data sets
All of the data used in the text is available in computer readableform. 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 todownload a complete set of files to keep on your hard drive. They willall fit on a single 1.44M floppy disk.

Oehlert Solutions Manual
This book by Gary W. Oehlert was first published in 2000 by W. H. Freeman.As of summer 2010, it has gone out of print. Curiously, I still like thisbook and would prefer to continue using it in my teaching; some of mycolleagues feel the same way. And since the copyright has (will soon) revertedto me, we can do that.
As of October 2010, you may now download a PDF of the complete textfrom this page. The book is Copyright © 2010 by Gary W. Oehlert,but I am distributing it under a Creative Commonslicense. Briefly, youare free to copy, distribute, and transmit this work provided the following conditions are met:
- You must properly attribute the work.
- You may not use this work for commercial purposes.
- You may not alter, transform, or build upon this work.

You may download A First Course in Design and Analysis of Experimentsby clicking here (1.9 MB PDF).
Download Data
The data fromA First Course in Design and Analysis of Experimentsare available in various formats:
Individual data sets can be accessed over the web asplain text files with labelled columns using a URL like
http://www.stat.umn.edu/~gary/book/fcdae.data/xxxx
The xxx takes the form of exmpl3.2 for example 2 from chapter 3,ex2.5 for exercise 5 from chapter 2, and pr13.14 for problem 14from chapter 13. You can access these directly from R via, for example,
read.table('http://www.stat.umn.edu/~gary/book/fcdae.data/exmpl3.2',header=TRUE)
All of the individual text data sets accessible via the web as aboveare also available in a single zip archive
Russ Lenth at the University of Iowa has also provided an R package thatinclude the data sets from the book.
oehlert_1.02.tar.gz
Download the package and save the file into a place where R can find it(e.g., your home directory or the desktop). Start R, set the workingdirectory to that location (e.g., use setwd(), and then use
install.packages('oehlert_1.02.tar.gz',repos=NULL,type='source')
(The repos=NULL says not to find it online but to look for thepackage in the local files; the type='source' tells R the file format.)Once the package is installed, you can do
library(oehlert)
from within R to load all of the data. At that point, the command
pr17.4
should give you problem 4 from chapter 17.
Note that the data set names, variable names, and variable codingsin oehlert.Rdata and the direct-web-accessible data may not be the same.
oehlert-data.sas An Ascii text filein SAS format. Oehlert-SAS.zip A zip archiveof individual SAS data files.Again, thanks to Russ Lenth for these files.
Single text fileThis is in the MacAnovamatread format.
Both the SAS data format and the MacAnova matread format areplain text files. You can download either and then cut/paste if youneed to put the data into another format.
