The coordinators of the nonstandard errors project, which came out earlier this year in the Journal of Finance (the full paper is here: https://doi.org/10.1111/jofi.13337), have produced a short video explaining the main findings. The video is part of a website providing access to data and other materials that we used in the research project: https://nonstandarderrors.com/. The video (and the paper for those with more interest in the details) is a useful resource for those teaching data science or quantitative research methods.
