In ForceChoice: Forced-Choice Modeling Based on Item Response Theory and Cognitive Diagnostic Models

Multivariate normal quadrature grid with Cholesky-stabilised weights

Description

Used by all continuous-trait logLik() methods.

Usage

make_quadrature_grid_mvn(
  Corr,
  theta.mu,
  D,
  L = NULL,
  theta.low = -6,
  theta.up = 6
)

Arguments

Corr	D x D correlation matrix (can be NULL for identity).
theta.mu	Numeric vector of length D (latent mean).
D	Number of dimensions.
L	Number of quadrature points per dimension, or NULL to auto-select from a built-in table.
theta.low, theta.up	Quadrature range.

Value

A list with theta.norm (grid matrix) and pi (normalised prior-weight column vector).
