This package is intended to be a "plug-and-play" tool for Bayesian Item Response Modeling. Currently, specific unidimensional IRMs are implemented, but future versions will aim on adding more flexibility to intermediary and advanced users.
birm depends on LaplacesDemon, an open-source statistical package that is intended to provide a complete environment for Bayesian inference.
This package should be considered experimental in this point of development. The following models are implemented:
rasch
function)pcm
function)rsm
function)plm
function)sirm
function)optscr
function)ggum
function)fishburn
function)rpcm
function)All of the following estimation methods are available to use:
method = "LA"
argument)method = "VB"
argument)method = "MCMC"
argument)method = "PMC"
argument)method = "IQ"
argument)method = "MAP"
and algo="SANN"
, algo="GA"
, algo="SD"
, or algo="ADAM"
; these methods were not originally implemented in LaplacesDemon)Using the 'remotes' package:
install.packages("remotes")
remotes::install_github("vthorrf/birm")
