Mean test lengths for six selected attribute vectors, π(α_c|X_i) = 0.65.

Note. Blue, red, and green represent the PWKL, MPWKL, and GDI, respectively. PWKL = posterior-weighted Kullback–Leibler index; GDI = G-DINA model discrimination index; G-DINA = generalized DINA; DINA = deterministic inputs, noisy “and” gate; DINO = deterministic input, noisy “or” gate; A-CDM = additive CDM; CDM = cognitive diagnosis model; HD-HV = high discrimination–high variance; LD-LV = low discrimination–low variance.
