In susanne-frick/MFCblockInfo: compute block information for multidimensional forced-choice questionnaires

MFC block information

Description

across persons and items

Usage

calc.info.block(
  FUN,
  traits = NULL,
  int,
  loads,
  uni,
  K,
  nb,
  which.blocks = NULL,
  responses = NULL,
  ...
)

Arguments

FUN	function to compute response probability
traits	matrix of traits, rows = persons, columns = traits
int	vector of item intercepts
loads	matrix of item loadings, rows = items, columns = traits
uni	matrix of item uniquenesses
K	numeric, number of blocks
nb	numeric, block size
which.blocks	vector, optional, indices of blocks to calculate info for, defaults to 1:K
responses	matrix of indices of observed rank orders, rows = persons, cols = blocks, defaults to NULL
...	other arguments passed to FUN

Value

list of length N, with entries (block,trait,trait) with Fisher (= expected) information; if observed information is required: list with two elements: expected and observed information, each is a list of length N, with entries (block,trait,trait)
