EAP score for dichotomous IRT item parameters

Description

EAP score for dichotomous IRT item parameters

Usage

eyeprocess_irt_eap_score(
  response,
  items,
  theta_grid = seq(-4, 4, length.out = 81),
  prior_mean = 0,
  prior_sd = 1,
  D = 1
)

Arguments

response	Observed item response or response variable.
items	Item-parameter data frame or item collection.
theta_grid	Grid of latent-trait values used for numerical scoring or integration.
prior_mean	Mean of the normal latent-trait prior.
prior_sd	Standard deviation of the normal latent-trait prior.
D	Logistic scaling constant.

Value

An object of class "eye_irt_score", stored as a named list, with components "estimate", "se", "theta", "posterior", "method". It contains eAP score for dichotomous IRT item parameters and associated metadata or diagnostics needed to interpret the result.
