SSC 2005 Saskatoon
Longitudinal Data Analysis – SSC Case Study 2005
Overview/abstract:
This case study introduces the students to the analysis of longitudinal data, using several different approaches (repeated measures, time varying covariates and growth curves to name a few) as well as introducing the student to the differences in model-based and design-based approaches to estimation. A sub-sample of the synthetic data file from the National Longitudinal Study on Children and Youth (NLSCY) is used to introduce the problems related to estimation and variance calculation in longitudinal surveys. Many issues relating to children’s behaviour and care are important concerns for Canadians and so the data set therefore was created with the objective that the student confronts a realistic situation in a longitudinal study and assesses the best way in which to analyze and present the data.
