+diagnosis modeling based on the generalized deterministic inputs, noisy and
+gate (G-DINA) model by de la Torre (2011) @url{doi:10.1007/s11336-011-9207-7}
+and its extensions, including the sequential G-DINA model by Ma and de la
+Torre (2016) @url{doi:10.1111/bmsp.12070} for polytomous responses, and the
+polytomous G-DINA model by Chen and de la Torre
+@url{doi:10.1177/0146621613479818} for polytomous attributes.  Joint attribute
+distribution can be independent, saturated, higher-order, loglinear smoothed
+or structured.  Q-matrix validation, item and model fit statistics, model
+comparison at test and item level and differential item functioning can also
+be conducted.  A graphical user interface is also provided.")
