  • The TwinLife Data Documentation is intended to give both an overview of the longitudinal twin family study TwinLife and a short instruction on how to use the TwinLife data. It corresponds to the contents of the ➔Short Guide.
    The following pages contain information about the project and links to various helpful documents that should facilitate the first steps into working with the TwinLife data. For a very quick description of everything you need to get started with the TwinLife Dataset see the Getting Started section below.
    All additional documents of data documentation are provided in the downloads section.
