| Abstract: | This article introduces a set of papers which illustrate the application or multivariate techniques to problems in aging research. Multivariate research strategies raise new issues in the choice of sample size that are discussed. The papers reviewed in this introduction are concerned with factorial invariance, the measurement of change, and various regression techniques useful in modeling developmental data. |
