dina 2.0.3

Bug fixes

• Fixed the likelihood computed in the internal update_alpha(), which applied an extra (1 - g) factor to every item a subject answered correctly. The factor was the same for every latent class, so it cancelled in the posterior, and samples from dina() are unchanged (#11).

dina 2.0.2

Changes

• Added explicit dependencies on R (>= 4.3.0), Rcpp (>= 1.1.0), and RcppArmadillo (>= 15.0.2-2)
• Removed CXX11 from src/Makevars and src/Makevars.win to avoid potential compilation issues with newer versions of Armadillo through RcppArmadillo.
• Switched README.Rmd to README.qmd to use Quarto for rendering.
• Fixed CITATION file to use c() instead of personList() and bibentry() to avoid CRAN check notes.
• Updated GitHub Action workflows.

dina 2.0.0

API Breakage

• The call to estimate with the gibbs sampling technique is now: dina(Y, Q, chain_length)

Changes

• Switched internal portions of the package to use the simcdm C++ routines and imported R level-routines.
• Switched from src/init.c to autogeneration via Rcpp 0.12.15
• Removed miscellaneous RNG seed.

Documentation

• Enabled markdown for inline documentiona with roxygen2.
• Improved documentation flow

Deployment

• Added TMSA Lab’s Travis-CI configuration for testing across R versions.
• Added Unit Tests for model reproducibility.
• Added code coverage results.
