Description

Approximation of the marginal log-likelihood of the 2 parameter logistic model using the Laplace approximation.

Usage

  irt2plikLA(par, X, fixed = NULL)

Arguments

par

Numeric vector of parameters (length 2*J).

X

Item matrix (J columns) containing only zeroes and ones.

fixed

Optional numeric vector (length J). If supplied, only NA entries in fixed will be estimated.

Details

Uses two Rcpp compiled functions: hbc and raschlik

Value

Returns the value of the marginal log-likelihood evaluated at par
