  "Description": "The PP package includes estimation of (MLE, WLE, MAP, EAP,\nROBUST) person parameters for the 1,2,3,4-PL model and the GPCM\n(generalized partial credit model). The parameters are\nestimated under the assumption that the item parameters are\nknown and fixed. The package is useful e.g. in the case that\nitems from an item pool / item bank with known item parameters\nare administered to a new population of test-takers and an\nability estimation for every test-taker is needed.",
