Estimation for a General Linear Model

Disclaimer of Warranties

Welcome to the estimation portion of the GLM program. Draft documentation for the program is available via this link.

As currently written this program can handle at most 400 rows and 75 columns in the design matrix. If this is insufficient for your purposes, please contact Steve Verrill at 608-231-9375 or at sverrill@fs.fed.us.

Before proceeding with the estimation you must provide design, data, and c prime matrix files. If you have already done so, you may proceed with the form below.

What is the name of the design matrix file?

What is the name of the data file?

What is the name of the c prime matrix file?

How many rows are there in the design matrix?
(400 or fewer)

How many columns are there in the design matrix?
(75 or fewer)

How many rows are there in the c prime matrix?
(75 or fewer)

What is the alpha for the individual confidence intervals on the c'bs?
(e.g., .05 for 95% confidence intervals)

What is the alpha for the joint (Scheffe) confidence intervals on the c'bs?
(e.g., .10 for joint 90% confidence intervals)

What name do you want for your results file?

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

Since you will see an html document that presents the results as soon as you execute the program, you may not want an ascii copy. However, we do provide this option.

The ascii file will be written in the pub/data anonymous ftp directory. If a file by the same name already exists in the directory, the new results will be appended to the existing file. Check the anonymous ftp link for directions about retrieving the file.

If ftp does not run on your machine, e-mail me at sverrill@fs.fed.us and ask me to e-mail the results file to you. Do this quickly as the pub/data directory is cleaned weekly.
