HLM by Scientific Software International, Inc.

What is it? HLM from Scientific Software International is a package that does Multilevel Models that are also often called Hierarchical Linear Models (HLMs). An example of a multilevel model is a regression equation showing how studying increases grades. That relationship may differ at different levels, such as teachers within schools within districts.

What can I use it for? Students, faculty, and staff can use HLM for university-related academic (not administrative) purposes. Use that benefits outside organizations requires the purchase of a commercial license.

Where can I run it? For UTK, HLM is available on OIT’s Apps@UT server and on the computers in the OIT public computer labs. There is a two simultaneous user limit for HLM.

How can I learn it? You can learn HLM from the Help files, which contain the entire manual. However, to understand the manual, you also need the book by the program’s developers, Raudenbush and Bryk, Hierarchical Liner Models, Applications and Data Analysis Methods. That book’s web page is at the company’s main web site.

Where can I get support? OIT offers Minimal Support for this software. We can help you analyze HLM models using other software that we fully support. For assistance, contact the OIT HelpDesk at 865-974-9900.
