Introduction

These vignettes illustrate how flexsurvPlus can be used to prepare inputs in R for inclusion into Excel based economic models.

Fitting parametric survival models in R
PSA and correlated endpoints (bootstrap approach)

Excel examples

These vignettes provide examples using some included Excel files to demonstrate a complete workflow.

Excel example 1 - extrapolation calculations
Excel example 3 - correlated endpoints in PSA

Methods appendix

These vignettes provide more details on the methods used and formulas for parametric forms and related surival and hazard functions.

Parametric survival analysis using the flexsurvPlus package: understanding the theory

STEM appendix

These vignettes describe how to convert to parametrizations that were used in a prior SAS macro. For most users this vignette can be safely ignored.
