hmetad 0.2.1

Bug fixes

• Additional arguments in type2_draws functions are now forwarded properly

Minor improvements and fixed

• Re-factored mean_confidence functions to call type2_draws/type2_probabilities functions for consistency

hmetad 0.2.0

CRAN release: 2026-08-21

New features

• Added allow_negative_values argument to fit_metad, which models M-ratio on the identity (rather than the logarithmic) scale to allow negative values of M-ratio
• Added ability to simulate with negative M-ratios. Note that the log_M arguments to simulation functions are renamed to reflect this
• Added functions for empirical quantities (i.e., type1_probabilities, type2_probabilities, joint_probabilities, roc1, roc2, and mean_confidence), allowing for easy comparison with model estimates
• Added functions for area under type 1 and type 2 ROCs (i.e., auroc1, auroc2, auroc1_draws, and auroc2_draws)
• Added a by_response argument to roc2_draws and related functions, allowing for type 2 ROCs collapsed across type 1 responses

Minor improvements and fixes

• Added .stimulus, .response, .confidence, and .joint_response arguments to all draws functions, allowing users to specify the names of the corresponding columns
• Confidence levels now match across the two type 1 responses in roc2_draws

hmetad 0.1.2

CRAN release: 2026-05-15

Bug fixes

• Resolved error in posterior_predict() and posterior_epred() for models with multilevel effects on a single confidence level
• cov_matrix() now works for scalar inputs
• aggregate_metad() now removes rows with NA values prior to aggregation

New features

• metac2_parameters() function streamlines setting priors for confidence criteria

Minor improvements and fixes

• aggregate_metad() and fit_metad() now perform more thorough checks on the number of confidence levels, K
• aggregate_metad() has increased efficiency

hmetad 0.1.1

CRAN release: 2026-04-20

Bug fixes

• Fixed bug in linpred_draws_metad/linpred_rvars_metad where meta_c only used first draw

New features

• Added logit option to use Stan’s multinomial_logit_lpmf/categorical_logit_lpmf

Minor improvements and fixes

• aggregate_metad() now preserves column types

• aggregate_metad() and fit_metad() now infer K using the maximum confidence level (instead of the number of unique levels)

• aggregate_metad() and fit_metad() now have more helpful errors/messages for invalid data arguments

• Minor updates to package documentation
