Longitudinal, Survival & Sensitivity Analysis

We assess changing responses and event timing while respecting dependence between observations. Analysis units, follow-up and missingness are reviewed before modelling.

What is included

  • Repeated-measures and mixed-effects models for trajectories and comparisons.
  • Survival analysis with explicit time-zero, event and censoring definitions.
  • Diagnostics, justified covariate selection and sensitivity to missingness and assumptions.

What you receive

  • Model specification and population/follow-up decisions.
  • Estimates, intervals, curves and diagnostics.
  • Reproducible code and interpretation of primary and sensitivity analyses.

Frequently asked questions

Can you review an already fitted model?

Yes. We examine specification, analysis population, assumptions and outputs to determine whether correction or redesign is needed.
