  "Description": "Allows the simultaneous analysis of responses and response\ntimes in an Item Response Theory (IRT) modelling framework.\nSupports variable person speed functions (intercept, trend,\nquadratic), and covariates for item and person (random)\nparameters. Data missing-by-design can be specified. Parameter\nestimation is done with a MCMC algorithm. LNIRT replaces the\npackage CIRT, which was written by Rinke Klein Entink. For\nreference, see the paper by Fox, Klein Entink and Van der\nLinden (2007), \"Modeling of Responses and Response Times with\nthe Package cirt\", Journal of Statistical Software,\n<doi:10.18637/jss.v020.i07>.",
