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.

Literature: The Multilevel Modeling

  • Bressoux, Pascal, Coustère, Paul & Leroy-Audouin, Christine (1997): Les modèles multiniveau dans l'analyse écologique: le case de la recherche en éducation, in: Revue française de sociologie, 38, 67-96.
    Some like it French: An introductory paper on multilevel analysis of educational achievement, with good data. No maths.

  • Bryk, A. S. & Raudenbush, S. W. (1992): Hierarchical Linear Models. Applications and Data Analysis Methods. Newbury Park, CA: Sage.
    Very good for those who wish to arrive at an advanced understanding.

  • DiPrete, Thomas A. & Forristal, Jerry D. (1994): Multilevel Models: Methods and Substance, in: Annual Review of Sociology, 20, 331-357.
    A good overview of the basic ideas and of applications, with most emphasis on random-coefficient models.

  • Ditton, Hartmut (1998): Mehrebenenanalyse. Grundlagen und Anwendungen des Hierarchisch Linearen Modells. Weinheim und München: Juventa.
    This book is specifically useful for those who want to analyze school data (and have to resort to books in German). However, readers of chapter 3 (dealing largely with centering) should consult chapter 5.2 in Kreft/de Leeuw 1998 and the paper by Kreft/de Leeuw/Aiken 1995.

  • Engel, Uwe (1998): Einführung in die Mehrebenenanalyse. Opladen: Westdeutscher Verlag (WV Studium 182).
    The wide coverage of this book has much to recommend it - for users who already have acquired an elementary understanding.

  • Goldstein, Harvey (1995): Multilevel Statistical Models. London: Arnold.
    A more advanced introduction by one of the " fathers" of multilevel modeling, now (2003) in its third ediation. An earlier version of the book can be downloaded here.

  • Hox, Joop (1995): Multilevel Analysis. Techniques and Applications. Mahwah, NJ: Erlbaum.
    This book is the expanded and updated version of an earlier book, Multilevel Analysis, Amsterdam: TT Publishers, 1995, which is downloadable for free (attention, this is a PDF file with a size of several MB).

  • Hox, Joop J. & Kreft, Ita G. G. (1994): Multilevel Analysis Methods, in: Sociological Methods & Research, 22, 283-299.
    This introduction to a special issue of SMR gives a brief overview of problems resulting from using traditional approaches for multilevel data, of the basic structure of the random coefficient model, of available software, and of current problems and possible future developments.

  • Kreft, Ita G. G. (1991): Using Hierarchically Linear Models to Analyse Multilevel Data. In: ZUMA-Nachrichten, 29, 44-56.
    A brief introduction that should be found in most German sociology libraries, but (naturally) cannot replace a textbook.

  • Kreft, Ita & de Leeuw, Jan (1998): Introducing Multilevel Modeling, London: Sage.
    This is certainly the most helpful textbook for those with a strong dislike of maths, formal derivations and the like. The reader is carefully guided through a number of examples. However, one should be aware that there are many advanced topics that are not dealt with in this book.

  • Longford, N. (1993): Random coefficient models. Oxford: Oxford University Press.
    In this book, statistical reasoning is paramount, but it is also applied to several datasets with helpful discussions of the results.

  • Ohr, Dieter (1999): Modellierung von Kontexteffekten: Voraussetzungen, Verfahren und eine empirische Anwendung am Beispiel des politischen Informationsverhaltens, in: ZA- Information 44, 39-63.
    A fine brief introduction, but I feel that it is somewhat infortunate that MM is introduced via an example where the gains from using a MM approach are almost nil (statistically speaking, i.e. the MM analysis barely differs from OLS regression results).

  • Snijders, Tom & Bosker, Roel (1999): Multilevel Analysis. An introduction to basic and advanced multilevel modeling. London, Thousand Oaks: SAGE.
    This is a very thorough introduction that requires quite some effort on part of the student - but it pays. Especially chapters 8 and 9 should be studied carefully, as I have found no comparable discussion of heteroscedascity and the basic assumptions (and how to check them) of multilevel modeling.

    [下载]Stefan Lundbergh and Timo Teräsvirta: Evaluating GARCH models

    Evaluating GARCH models

    Stefan Lundbergh and Timo Teräsvirta,

    Department of Economic Statistics, Stockholm School of Economics, P.O. Box 6501, SE-113 83, Stockholm, Sweden

    Available online 12 June 2002.



    Abstract

    In this paper, a unified framework for testing the adequacy of an estimated GARCH model is presented. Parametric Lagrange multiplier (LM) or LM type tests of no ARCH in standardized errors, linearity, and parameter constancy are proposed. The asymptotic null distributions of the tests are standard, which makes application easy. Versions of the tests that are robust against nonnormal errors are provided. The finite sample properties of the test statistics are investigated by simulation. The robust tests prove superior to the nonrobust ones when the errors are nonnormal. They also compare favourably in terms of power with misspecification tests previously proposed in the literature.

    Author Keywords: Conditional heteroskedasticity; Model misspecification test; Nonlinear time series; Parameter constancy; Smooth transition GARCH

    Stochastic Limit Theory:An Introduction for Econometricians


    Publication date 1994 (this edition)
    Print ISBN-10: 0-19-877403-6
    Print ISBN-13: 978-0-19-877403-7
    doi:10.1093/0198774036.001.0001



    Abstract:

    This book aims to introduce modern asymptotic theory to students and practitioners of econometrics. It falls broadly into two parts. The first half provides a handbook and reference for the underlying mathematics (Part I, Chapters 1-6), statistical theory (Part II, Chapters 7-11) and stochastic process theory (Part III, Chapters 12-17). The second half provides a treatment of the main convergence theorems used in analysing the large sample behaviour of econometric estimators and tests. These are the law of large numbers (Part IV, Chapters 18-21), the central limit theorem (Part V, Chapters 22-25) and the functional central limit theorem (Part VI, Chapters 26-30). The focus in this treatment is on the nonparametric approach to time series properties, covering topics such as nonstationarity, mixing, martingales, and near-epoch dependence. While the approach is not elementary, care is taken to keep the treatment self-contained. Proofs are provided for almost all the results.
