riwishart

Creates a random inverse wishart distribution when given
degrees of freedom and a sigma matrix.

Jointly model the accuracy of cognitive responses and item choices
within a Bayesian hierarchical framework as described by Culpepper and
Balamuta (2015) <doi:10.1007/s11336-015-9484-7>. In addition, the package
contains the datasets used within the analysis of the paper.
