| Title: | Automating the Creation of Stan Code for TDCMs |
| Version: | 3.0.0 |
| Description: | A collection of functions for automatically creating 'Stan' code for transition diagnostic classification models (TDCMs) as they are defined by Madison and Bradshaw (2018) <doi:10.1007/s11336-018-9638-5>. This package supports automating the creation of 'Stan' code for TDCMs, fungible TDCMs (i.e., TDCMs with item parameters constrained to be equal across all items), and multi-threaded TDCMs. |
