As you prepare for your final exam, please note the following:

(a) what to bring to the exam:
1. Books, notes, homework, labs and so forth if you want.
2. A hand calculator is required.
3. Statistical tables with F-distributions, chi-square distributions are required (feel free to bring any book
you want that has statistical tables).

(b) What kind of questions
The exam will consist of two parts:
(1) design identification where you will identify fixed/random factors, the design type and the experimental unit or sampling unit depending on the question.

(2) Short questions on model formulations with normal/non-normal responses, testing effects, partitioning degrees of freedom, determining expected mean squares, comparing models (non-nested/nested) and so forth.

As you can see the exam will be comprehensive with short questions overall. Portions of SAS output or key pieces of information will be provided for questions needing computations.

I hope this information is helpful.

Monday, 03/10/2008

(1) Today's lecture notes: posted.

(2) Homework #6 research questions: posted.

(3) Prelim I information:

Part I:
your research questions for Homework #5 & #6 and a third research paper on a split plot split plot design. Make sure to clearly identify the factors and their levels in each case. No need to discuss the type of factors (fixed vs. random). You will turn in a hard copy showing the SAS code used for designing each research question. No SAS output is needed. So do not include the SAS output. Email your SAS file and your MS word document file to Freedom as instructed.

Part II:
seven questions will be given on design identification. You will need for each question to identify fixed and/or random factors beside identifying the appropriate design. I suggest you do not bring any books to the exam as it won't be helpful. However, feel free to bring your lecture/homework /lab material if you want.

Thursday, 03/06/2008

(1) Homework #6: the SAS FACTEX procedure does not generate Graeco-Latin square for v =12.
However, with the exception of a 6 by 6, a Graeco-Latin square design exists when the size is not divisible by 2 or when the size is divisible by 4 (see Cochran, 1958, p.209). GenStat is more flexible than SAS and does produce a Graeco-Latin square for v =12.

(2) Homework #6 research question MS Word document/file: due by an attachment email to me prior to turning in a hard copy as instructed during lecture this week.

(3) Prelim I information:

Part I:
your research questions for Homework #5 & #6 and a third research paper on a split plot split plot design. Make sure to clearly identify the factors and their levels in each case. No need to discuss the type of factors (fixed vs. random). You will turn in a hard copy showing the SAS code used for designing each research question. No SAS output is needed.

Below are very interesting questions from one of your classmates.
 
I have some concerns about Part 2 of Question #1 of Homework #1.
If I should be approaching this problem the way we approached Lab #1,
will I have a "PATIENT" column numbered 1-30 (in sequential order) similar to that
of "Subjects" from Lab #1?

Yes, you need to follow instructions for Lab #1. You also need to create an MS Excel file Patient.xls containing the patients IDs. File Patient.xls has the variable PATIENT labeled from 1 to 30.Thus the variable PATIENT is imported into the ADX design.

If this is so, do we manually go in and "type in" the numbers 1 through 30 under the PATIENT
column (because there is no "PATIENTS" excel file to import these ID's for us)?
As mentioned above, the IDs for the patients are imported from an MS Excel file Patient.xls that you need to create. Again, make sure to create the Excel data set file Patient.xls containing IDs for the patients.

And also, should the columns under NMIGHEAD, HEADIND1, and HEADIND2 have no data (just the designations I have just mentioned)?
Yes, the columns NMIGHEAD, HEADIND1, and HEADIND2 created in ADX are empty because the researcher does not have the data to enter at this point. He/she is designing the experiment and the data will be entered later on when available.
