Full Description

This examination addresses the importance of evaluating statistical assumptions in Longitudinal Data Analysis models. Key areas include normality, homoscedasticity, and independence of errors.

The integrity of statistical findings hinges on these assumptions, which influence the validity and reliability of conclusions drawn from health studies, thereby impacting public health decisions.

Students will articulate the importance of these assumptions and demonstrate their ability to identify violations, as well as discuss implications for analysis outcomes.

Candidates are encouraged to utilize specific examples from existing literature to substantiate their understanding of the role of assumptions in data interpretation.

Sample Questions

  • What steps would you take to assess the normality assumption in your longitudinal dataset?
  • How can the violation of homoscedasticity affect the outcomes of a longitudinal analysis?
