Data

Whenever possible and/or appropriate, I archive and make available data used in published articles. Unless they ask me to, I do not post datasets where my co-authors did most/all the work in data collection or sample construction, but feel free to get in touch me or them to discuss availability (usually, I will pass your email on to my co-author).
