Wolfgang Ludwig-Mayerhofer:The Multilevel Modeling Page

What is Multilevel Modeling?

Multilevel modeling (MM) is a family of statistical procedures that try to come to terms with influences that are located on different, well, levels. So naturally the question arises what is meant by "level".

One way to think about it is as follows: People do not live entirely on their own, but rather embedded in social units. Even though today, in a globalized world, we may say that people have relationships with other people all over the world, most people have some relationships that are more special than others. People who are linked together via special relationships frequently communicate among each other, and thus the possibility rises that the people you are linked to influence your views. So we may think about the individuals as one (the lowest) level and their network (whether it consists of people that are met in person or of people communication with whom may take place only via artifical media) as a next (higher) level.
(Note that " low" and " high" are just names; we may well think about things the other way round. "High" just means something like "aggregate"; that is, several individuals -- entities on the "low" level -- are seen as agglutinated).

A second way: Opportunities structure the behaviour of individuals, and as many people select their opportunities by local proximity, the region in which a person lives may enhance or restrict his or her opportunity. For instance, if a person lives in a region with high unemployment, this may influence his or her behaviour about acceptable wage levels when looking for a new job.

A third way: Often people, be it voluntarily or not, are subject to common external influences. Take, for instance, a university professor. All the students that come to her or him are subject to her or his way of teaching. Could be that this way of teaching influences these students (even though this certainly -- if sometimes fortunately -- happens less frequently than we professors might desire). Therefore, again we may think of a multitude of professors as the "higher" level units and of their many students as the "lower" level units.

For a variety of reasons, data referring to more than one level often cannot be analyzed by conventional statistical models. For instance, classical OLS regression analysis requires that residuals from individual observations are not correlated. This requirement becomes doubtful if these individual observations are subject to the same influences or are related to each other in other ways.

After so many words, this page -- at the moment -- does very little: It provides a few links to MM related pages, and it also provides selected references to the literature, with short comments.
