WHAT IS INSIDE

A reproducible path through the workflow.

01

Audit the schedule

Describe waves, missing outcomes, complete profiles, and model contributors.

02

Fit corrected ANOVA

Calculate Greenhouse–Geisser corrected inference.

03

Test multivariate change

Evaluate successive changes without sphericity.

04

Model individual growth

Estimate quadratic change and confidence-banded trajectories.

SCOPE AND BOUNDARIES

Match the workflow
to the question.

Before adapting the example:

  • Run the complete synthetic workflow.
  • Use only a de-identified working copy.
  • Document assumptions and analysis decisions.
  • Review the model with the committee.

The methods use different samples, assumptions, and estimands. Select one from the design and question rather than the smallest p-value.
