Joint\nattribute distribution can be independent, saturated,\nhigher-order, loglinear smoothed or structured. Q-matrix\nvalidation, item and model fit statistics, model comparison at\ntest and item level and differential item functioning can also\nbe conducted. A graphical user interface is also provided. For\ntutorials, please check Ma and de la Torre (2020)\n<DOI:10.18637/jss.v093.i14>, Ma and de la Torre (2019)\n<DOI:10.1111/emip.12262>, Ma (2019)\n<DOI:10.1007/978-3-030-05584-4_29> and de la Torre and Akbay\n(2019).",
