WHAT IS INSIDE

A reproducible path through the workflow.

01

Review the complete series

Assess level, trend, variability, immediacy, overlap, consistency, and replication.

02

Summarize phase changes

Calculate immediacy, NAP, rank-biserial effects, and PND.

03

Fit segmented regression

Estimate level and slope changes with Newey–West uncertainty.

04

Probe sensitivity

Compare AR(1) results and simulate designs under explicit assumptions.

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.

One short series does not establish a population effect. Statistical summaries supplement visual analysis and design logic.
