In idealstan: Generalized IRT Ideal Point Models with 'Stan'

Release v0.7.2

• Updated to be compatible with most recent rstan (version 2.19.2).
• Added id_plot_cov function for marginal effects plotting of covariates.
• Added id_plot_irf for calculating impulse-response functions for AR(1) models covariates.

Release v0.7.1

• Fixed bug where time series vignette did not show on CRAN screen

Release v0.7.0

• Implement a Gaussian process prior for ideal points to permit semi-parametric inference
• Update id_plot_legis_dyn to allow for overlay plots comparing different time series models
• Strength over-time model identification using variational inference fits

Release v0.6.0

• Set a stricter threshold for vb to 1e-04 to promote more robust variational inference

Release v0.5.1

• Fixed bugs in plotting functions related to plotting two groups.
• Fixed bug in AR(1) model with restricted time variance.
• Updated dependencies to rstan 2.18.2.
• Added error-catching in covariate creation.

Release v0.5.0

• New models for Poisson, ordinal-graded response, Normal and Log-normal outcomes.
• Time-varying ideal point processes: random-walks and auto-regressive priors.
• Time-varying plot functions for ideal points.
• Hierarchical covariates for ideal points and item/bill discrimination.
• Switched from matrix data input to long data frames.

Release v0.2.9.1

• Fixed bugs in id_extract and id_make functions.

Release v0.2.9

• Fixed a bug in the ideal point plot function, and also in the auto_id option in id_estimate.

Release v0.2.2

• First release on CRAN.
• Fixed documentation issues from v0.2.1
• All vignettes now building properly.
