Algorithm | Time (old, in ms) | Time (new, in ms) |
---|---|---|
PWKL | 20 | 19 |
MPWKL | 142 | 22 |
PWCDI | 144 | 23 |
MI | 55 | |
SHE | 28 |
Note. “Old” refers to the calculation strategy in which the matrix D is not pre-calculated and “new” is otherwise.
PWKL = posterior-weighted Kullback–Leibler information method; MPWKL = modified posterior-weighted Kullback–Leibler information method; PWCDI = posterior-weighted cognitive diagnostic model discrimination index; MI = mutual information method simplified as in Wang (2013).
