Changelog

Source: NEWS.md

irw 1.2.0

irw 1.1.2

• Drop release PRs from the generated NEWS.md entry (#142)
• Move redivis to Suggests and check for it at runtime (#141)

irw 1.1.1

• Compare release timestamps in UTC so NEWS.md skips released PRs (#139)
• Strip the arrow namespace reference from swmd_mokken.rda (#138)

• Don’t fail release-prepare when Actions can’t open the PR (#136)

irw 1.1.0

New features

• irw_imv() computes the InterModel Vigorish, and irw_predict() returns per-response predicted probabilities from a fitted mirt model. Together they support out-of-sample model comparison, walked through in the new “Comparing Models Out of Sample with the IMV” article (#131, #130).
• irw_set_version(), irw_get_version() and irw_reset_version() pin IRW data to a Redivis version, so an analysis can be reproduced against the data it was written for (#128).
• irw_collections(), irw_collection() and irw_collection_members() expose the curated groupings of IRW tables (#125).
• irw_recode(), irw_recode_key() and irw_decode() swap long identifiers for keyboard-friendly ones and back again (#123).
• irw_table_sets() summarizes the items and response values in a table with a server-side query, returning in seconds and without spending export quota. Exhausted quota is now reported as a quota error rather than a missing table (#121).

Changed behavior

• irw_simdata() draws default discriminations for model = "2PL" and "3PL" from lognormal(0, 0.5) rather than lognormal(0.2, 0.2). The old spread put the middle half of items between 0.95 and 1.25, which is a Rasch model in all but name; the new one keeps the median at 1 and widens that range to 0.7-1.4. Simulated data changes for a fixed seed when a is not supplied — pass a = rlnorm(n_item, 0.2, 0.2) for the old behavior (#132).

Documentation and infrastructure

• New article pairing IRW data with mirt, ltm, psychotools and other psychometrics packages (#124), and a pointer to the IRW project map (#127).
• Item text table names now resolve case-insensitively (#122).
• Tag splitting is unified on one parser (#126).
• Collections table references re-pinned to current Redivis IDs (#129).
• Releases are cut from the Actions tab: a workflow bumps the version, writes this file and opens a release PR, and merging it tags and publishes (#133, #134).
