makeTest-methods

Generate a test object

Description

makeTest is a function for creating a test object. This is used in Shadow to determine all necessary data prior to the main simulation, so that they are not affected by random number generation.

Usage

makeTest(
  object,
  theta = seq(-4, 4, 0.1),
  info_type = "FISHER",
  true_theta = NULL
)

## S4 method for signature 'item_pool'
makeTest(
  object,
  theta = seq(-4, 4, 0.1),
  info_type = "FISHER",
  true_theta = NULL
)

Arguments

`object`	an `item_pool` object.
`theta`	a grid of theta values.
`info_type`	the type of information.
`true_theta`	(optional) true theta values to simulate response data.

Examples

test <- makeTest(itempool_science, seq(-3, 3, 1))
