Groundhog was funded by the Wharton School of the University of Pennsylvania.
Like AsPredicted, ResearchBox, AsCollected groundhog is brought to you by the Wharton Credibility Lab.
Uri Simonsohn (.htm) wrote the first version of groundhog and then collaborated with Hugo Gruson, an evolutionary biologist (htm), to refine it, improve it, and turn it into a CRAN package. Uri is the sole maintainer of groundhog since version v1.2.0.
