Datasets and Derived Variables
The DAM Core maintains internal versions of certain datasets alongside derived variables that CAsToR personnel may request access to. These data are intended for research collaboration within CAsToR and to ensure consistency across CAsToR analyses. Per the terms of use of the data providers, these data may not be further disseminated or redistributed.
The DAM Core also maintains derived variables developed for previous CAsToR analyses, such as approximations of pack-years, product use variables that incorporate the answers to multiple questions, etc. The DAM Core team maybe be able to derive new variables for you as part of a data request.
