A longitudinal study (or longitudinal survey, or panel study) is a research design that involves repeated observations of the same variables (e.g., people) over long periods of time (i.e., uses longitudinal data). It is often a type of observational study, although it can also be structured as longitudinal randomized experiment. [1]
NCES has continued the National Education Longitudinal Studies program with five additional longitudinal cohort studies, as of 2022. [19] These studies are separated by roughly ten years each and were designed to also be nationally representative and comparable to the data measured and collected in NLS-72. [20]

In social sciences, sequence analysis (SA) is concerned with the analysis of sets of categorical sequences that typically describe longitudinal data. Analyzed sequences are encoded representations of, for example, individual life trajectories such as family formation, school to work transitions, working careers, but they may also describe daily ...
Such longitudinal data share the features that the same subjects are observed repeatedly over time, and on the same tests (or parallel versions), and at known times. In latent growth modeling, the relative standing of an individual at each time is modeled as a function of an underlying growth process, with the best parameter values for that ...
The National Longitudinal Survey of Youth 1997 (NLSY97), the newest survey in the NLS program, is a sample of 8,984 young men and women born during the years 1980 through 1984 and living in the United States when first interviewed. Survey respondents were ages 12 to 17 when first interviewed in 1997.

Generalized linear mixed models provide a broad range of models for the analysis of grouped data, since the differences between groups can be modelled as a random effect. These models are useful in the analysis of many kinds of data, including longitudinal data .
