  "Description": "An implementation of the generalized graded unfolding\nmodel (GGUM) in R, see Roberts, Donoghue, and Laughlin (2000)\n<doi:10.1177/01466216000241001>). It allows to simulate data\nsets based on the GGUM. It fits the GGUM and the GUM, and it\nretrieves item and person parameter estimates. Several plotting\nfunctions are available (item and test information functions;\nitem and test characteristic curves; item category response\ncurves). Additionally, there are some functions that facilitate\nthe communication between R and 'GGUM2004'. Finally, a\nmodel-fit checking utility, MODFIT(), is also available.",
