Allocation of Specimens, Complex Experiment

What is the name of your data file?

The name should be unique to you to prevent the file from being accidentally overwritten by another user.

The first rows of your data file must contain the names of the factor levels. For example, if you want to conduct a 3x2x2 analysis of variance (3 factors, 3 levels in the first factor, 2 levels in the second and third factors), the first row should contain the names of the three levels of the first factor, e.g.,

small medium large

They must be separated by blanks (and, of course, can contain no blanks). The second row must contain the names of the two levels of the second factor, e.g.,

cold hot

The third row must contain the names of the two levels of the third factor, e.g.,

wet dry

Level names can contain no more than 10 characters.

After the names of the levels, the remaining rows of the data file must each contain two items. The first column must contain a specimen ID. The specimen ID's must not contain blanks. Only the first 20 characters of the ID's will be retained in the output. The second column must contain the predictor value for the specimen. There may be no more than 5000 specimens.

Before you proceed, you must transfer this data file to www1.fpl.fs.fed.us via anonymous ftp. You must place it in the pub/tt directory. (If ftp does not run on your machine, e-mail your data to sverrill@fs.fed.us and ask me to place it in the appropriate anonymous ftp directory. I will do so and notify you via e-mail. You can then run the Tight T program over the Web.)

What is the name of your data file?

How many factors are there?
(e.g., 3 for a three-way ANOVA)

How many levels are there?
(e.g., 3 2 2 for a 3x2x2 ANOVA. There must be a total of 25 or fewer levels.)

How many replicates are there per factor combination?
(e.g., to have 5 replicates in a 3x2x2 ANOVA, a total of 5x3x2x2 specimens would be required.)

What is the starting value for the random number generator?
(It must be a positive integer less than 1000000000.)

The "random" numbers that are generated are exactly determined by the starting value. Thus, if you want a different set of "random" numbers, you must supply a different starting value.
