We, [Judith Singer](https://www.gse.harvard.edu/faculty/judith-singer) and [John B. Willett](https://www.gse.harvard.edu/faculty/john-willett)*,* welcome you to the webpage that we have created to support our book, *Applied Longitudinal Data Analysis (ALDA)*, New York: [Oxford University Press](https://global.oup.com/academic/?cc=us&lang=en&), March 2003.

We intend *ALDA* to be a professional book for empirical researchers and graduate students in the behavioral, social, and biomedical sciences. It offers an accessible in-depth presentation of two popular statistical methods for analyzing longitudinal data: multilevel modeling of individual change and hazard/survival modeling for event occurrence in both discrete- and continuous-time.

In *ALDA*, using real data from published studies, we take you step-by-step through complete longitudinal data-analyses, from exploratory strategies for displaying your data sensibly to the specification, fitting, and interpretation of complex statistical models.
