Resources related to the weighting of data in the ABCD Study.
Materials developed by William Pelham (UCSD) for use in weighting ABCD data, to improve sample or subsample generalizability and/or deal with longitudinal attrition.
Most materials were developed for a workshop deliver in March 2022 and are offered as-is.

I recommend reading through intro-to-weighting-slides.pptx first, then looking at 2022-weighting-workshop.zip. 2021-weighting-demo.zip is old, has been superseded by 2022-weighting-workshop.zip, but is included here for completeness.
-
intro-to-weighting-slides.pptx. Slides from workshop giving tutorial on use of weighting in ABCD. -
2022-weighting-workshop.zip. A repository with examples of how to do weighting in ABCD data usingR. Look at the fileRUNME.Rfirst. These scripts were created for use with the ABCD 4.0 release from NIDA. -
2021-weighting-demo.zip. Examples of how to do weighting in ABCD data that I made previously. These scripts were created for use with the ABCD 3.0 release from NDA. Thus,2022-weighting-workshop.zipis a more thorough and up-to-date version... I include these files here as a backup resource as I may have explained the process or implemented the code slightly differently here.
