calc_info_FB(x, items_list, ncat, model, useEAP = FALSE)

Arguments

• x: A numeric vector of MCMC sampled theta values.
• items_list: A list of item parameter matrices.
• ncat: a numeric vector specifying the number of response categories in each item.
• model: a numeric vector indicating the IRT models of each item (1: 1PL, 2: 2PL, 3: 3PL, 4: PC, 5: GPC, 6: GR).
• useEAP: TRUE to use the mean of MCMC theta draws.
