(Internal) Compute item information at current theta estimate

Description

computeInfoAtCurrentTheta is an internal function for computing item information at current theta estimate.

Usage

computeInfoAtCurrentTheta(
  item_selection,
  j,
  current_theta,
  item_pool,
  model_code,
  info_fixed_theta,
  info_grid,
  item_parameter_sample
)

Arguments

item_selection	the item_selection slot of a config_Shadow object.
j	the examinee index.
current_theta	a named list containing current theta estimate.
item_pool	an item_pool object.
model_code	machine-sanitized item model codes for passing onto C++ functions.
info_fixed_theta	a list containing item information at prespecified theta points.
info_grid	a matrix containing item information across quadrature points.
item_parameter_sample	a list containing item parameter samples for Bayesian estimation.
