In nando11235813/raschreg: Item Response Theory models including explanatory variables of the ability parameter

Description

Approximate the marginal log-likelihood of a Rasch regression model using Laplace approximation.

Usage

  raschreglikLA(par, X, Z, fixed = NULL)

Arguments

par	Numeric vector of parameters (length J+p).
X	Item matrix (J columns) containing only zeroes and ones.
Z	Regression matrix (p columns).
fixed	Optional numeric vector (length J). If supplied, only NA entries in fixed will be estimated.

Details

Uses two Rcpp compiled functions: huc and raschreglik

Value

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