Collaborators Several projects in the psychonetrics lab are funded by the Amsterdam Centre for Urban Mental Health. We work closely together with the Jasp team, which works on developing an open-source graphical software package for state-of-the-art statistical analyses. Our lab is closely linked, and partially overlapping, with the Psychosystems labgroup. We work closely together with the Oefenweb team, especially in regard to work related to adaptive testing. Several projects of the psychonetrics lab are in close collaboration with the ilab at the University Medical Center Groningen.
