The vignette introduces a technique for coping with the problem of systematically missing data in longitudinal social and political surveys.
The project combines many aspects of open science:
* The multiple imputation procedure was implemented in R, a programming language and free software environment for statistical computing.
* The text and the code of the vignette were prepared in R markdown, a form of literate programming. Literate programming makes research more transparent and reproducible. It is also a nice tool for the development of open educational resources (OER).
* Finally, all the material of the vignette is on my [GitHub][1] page, where users can clone the repository, comment, and suggest modifications.
