Shadow: Run adaptive test assembly.

Description

Perform adaptive test assembly based on generalized shadow-test approach, with specified configurations.

Usage

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

Arguments

config

A '>config_Shadow object.

constraints

A list representing optimization constraints. Use loadConstraints for this.

true_theta

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

data

Numeric. A matrix containing item response data.

prior

Numeric. A matrix or a vector containing priors.

prior_par

Numeric. A vector of parameters for prior distribution.

session

Used to communicate with a Shiny session.
