ty_administer: Administer a two-stage MST to simulated examinees

In throughyear: Linking, Routing and Fairness for Through-Year Assessment

Administer a two-stage MST to simulated examinees

Description

Routing uses the EAP after the (possibly shortened) routing module under 'route_prior'. With 'routing_n = 0' the routing decision uses the prior alone. The final score is the EAP over all administered items under 'score_prior'. Priors are lists with 'mean' and 'sd' (scalars or one value per examinee).

Usage

ty_administer(
  mst,
  theta,
  route_prior,
  score_prior,
  routing_n = NULL,
  grid = seq(-5, 5, by = 0.05),
  seed = NULL
)

Arguments

mst	A 'ty_mst'.
theta	True abilities.
route_prior, score_prior	Priors for routing and for scoring.
routing_n	Routing items used (default: all).
grid	Theta grid.
seed	Optional seed.

Value

Data frame: 'module', 'correct_module' (most informative module at the true theta), 'route_eap', 'theta_hat', 'se', 'n_items'.

Examples

mst <- ty_mst_default()
pop <- list(mean = 0, sd = 1)
res <- ty_administer(mst, theta = rnorm(500), route_prior = pop, score_prior = pop, seed = 1)
mean(res$module == res$correct_module)   # routing accuracy
