The study was originally funded by the United States Department of Education ’s National Center for Education Statistics (NCES) as a part of their Secondary Longitudinal Studies Program .
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]
Major advances in this field can result from advances in learning algorithms (such as deep learning), computer hardware, and, less-intuitively, the availability of high-quality training datasets. [1] High-quality labeled training datasets for supervised and semi-supervised machine learning algorithms are usually difficult and expensive to ...
Panel data is a subset of longitudinal data where observations are for the same subjects each time. Time series and cross-sectional data can be thought of as special cases of panel data that are in one dimension only (one panel member or individual for the former, one time point for the latter). A literature search often involves time series ...
Data are available for this cohort through 2014 when the 7,071 men and women in the sample were ages 49 to 58. Data from the 2016-2017 survey will be released in late 2018/early 2019. To supplement the main data collection, survey staff conducted special high school and transcript surveys.
