Package: mfrmr Type: Package Title: Estimation and Diagnostics for Many-Facet Measurement Models Version: 0.2.4.9000 Config/mfrmr/release-status: development Config/mfrmr/public-version: 0.2.4 Authors@R: person(given = "Ryuya", family = "Komuro", role = c("aut", "cre", "cph"), email = "ryuya.komuro.c4@tohoku.ac.jp", comment = c(ORCID = "0000-0001-9205-0926")) Description: Estimates many-facet ordered-response measurement models with arbitrary facet counts, rating-scale and partial-credit parameterizations, a generalized partial-credit extension with discrimination varying across levels of one selected facet. Marginal maximum likelihood permits a different facet to own category steps; joint maximum likelihood requires the same facet for both roles. Conditional maximum likelihood fits many-facet rating-scale and partial-credit models by conditioning on person totals, with structural contrast intervals and no assumed ability distribution. Experimental two-family estimation and conditional scoring retain explicit uncertainty limitations. The fit, diagnose and report workflow covers anchoring, linking, bias and differential-functioning screening, with saved results for replay. Observed-score G-Study and D-Study analyses support assessment planning under declared rating designs. Agreement, rater feedback and conditional classification summaries connect analysis to assessment decisions. See 'Andrich' (1978) , 'Masters' (1982) , and 'Muraki' (1992) for the underlying ordered-response models.
