Shadow: Run computerized adaptive testing with generalized shadow-test approach

Description

Run computerized adaptive testing with generalized shadow-test approach.

Usage

Shadow(object, config, true_theta = NULL, constraints = NULL,
  prior = NULL, prior_par = NULL, data = NULL, session = NULL)
# S4 method for item_pool
Shadow(object, config, true_theta = NULL,
  constraints = NULL, prior = NULL, prior_par = NULL, data = NULL,
  session = NULL)

Arguments

object

An '>item_pool object. Use loadItemPool for this.

config

A '>config_Shadow object.

true_theta

Numeric. A vector of true theta values to be used in simulation.

constraints

A list representing optimization constraints. Use loadConstraints for this.

prior

Numeric. A matrix or a vector containing priors.

prior_par

Numeric. A vector of parameters for prior distribution.

data

Numeric. A matrix containing item response data.

session

Used to communicate with a Shiny session.
