In TestDesign: Optimal Test Design Approach to Fixed and Adaptive Test Construction

Create a simulation data cache object

Description

makeSimulationDataCache is a function for creating a simulation_data_cache object. This is used in Shadow to make all necessary data (e.g., item information, response data) prior to the main simulation.

Usage

makeSimulationDataCache(
  item_pool,
  info_type = "FISHER",
  theta_grid = seq(-4, 4, 0.1),
  seed = NULL,
  true_theta = NULL,
  response_data = NULL
)

## S4 method for signature 'item_pool'
makeSimulationDataCache(
  item_pool,
  info_type = "FISHER",
  theta_grid = seq(-4, 4, 0.1),
  seed = NULL,
  true_theta = NULL,
  response_data = NULL
)

Arguments

item_pool	an item_pool object.
info_type	the type of information.
theta_grid	a grid of theta values.
seed	(optional) seed to use for generating response data if needed.
true_theta	(optional) true theta values of all simulees.
response_data	(optional) response data on all items for all simulees.
