Fit dynamic group-level item response theory (IRT) and multilevel
regression and poststratification (MRP) models from item response data. dgo
models latent traits at the level of demographic and geographic groups,
rather than individuals, in a Bayesian group-level IRT approach developed by
Caughey and Warshaw (2015) <doi:10.1093/pan/mpu021>. The package also
estimates subpopulations' average responses to single survey items with a
dynamic MRP model proposed by Park, Gelman, and Bafumi (2004)
<doi:10.11126/stanford/9780804753005.003.0011>.
