create_E_MFI {cat.dt} | R Documentation |
Computes a vector of the Fisher Information of every item allocated to the specified level node in the CAT decision tree. Every FI is computed using the estimated ability level in the specified node
create_E_MFI(bank, theta_est, nres, C)
bank |
matrix of the item bank. Rows represent items, and columns
represent parameters. If the model is |
theta_est |
estimated ability level |
nres |
vector of number of possible responses for every item |
C |
