This vignette shows the package-native route from a fitted many-facet Rasch model to manuscript-oriented prose, tables, figure notes, and revision checks.
The reporting stack in mfrmr is organized around four
objects:
fit: the fitted model from fit_mfrm()diag: diagnostics from
diagnose_mfrm()chk: the revision guide from
reporting_checklist()apa: structured manuscript outputs from
build_apa_outputs()For a broader workflow view, see
vignette("mfrmr-workflow", package = "mfrmr"). For a
plot-first route, see
vignette("mfrmr-visual-diagnostics", package = "mfrmr").
Use reporting_checklist() first when the question is
“what is still missing?” rather than “how do I phrase the results?”

#> 4 Available; adapt this evidence into the manuscript draft after methodological review.
#> 5 Document the connectivity result before making common-scale or linking claims.
#> 6 Use standardized residuals as screening diagnostics, not as standalone proof of model adequacy.
#> 7 Run residual PCA if you want to comment on unexplained residual structure.
#> 8 Report facet reliability/separation directly in the APA results section.
#> 9 Use the fixed/random variability summary in the results text or table notes.
#> 10 Available; adapt this evidence into the manuscript draft after methodological review.Interpretation:
DraftReady flags whether the current objects already
support a section for drafting with the package’s documented
caveats.Priority shows what to resolve first.NextAction is the shortest package-native instruction
for closing the gap.mfrmr intentionally distinguishes
model_based, hybrid, and
exploratory precision tiers.

model_based.hybrid and exploratory outputs more
conservatively, especially for SE-, CI-, and reliability-heavy
prose.build_apa_outputs() is the writing engine. It returns
report text plus a section map, note map, and caption map that all share
the same internal contract.

#> Method.

#> Design and data.
#> The analysis focused on Writing assessment in Local scoring study. A many-facet Rasch model
#> (MFRM) was fit to 768 observations from 48 persons scored on a 4-category scale (1-4). The
#> design included facets for Rater (n = 4), Criterion (n = 4). The rating scale was described
#> as 0-4 rubric scale.
#>
#> Estimation settings.
#> The RSM specification was estimated using MML in the native R MFRM package. Model-based
#> precision summaries were available for this run. Recommended use for this precision
#> profile: Use for primary reporting of SE, CI, and reliability in this package..
#> Optimization converged after 51 function evaluations (LogLik = -903.081, AIC = 1824.161,
#> BIC = 1865.955). Constraint settings: noncenter facet = Person; anchored levels = 0
#> (facets: none); group anchors = 0 (facets: none); dummy facets = none.

#> Scale functioning.
#> Category usage was adequate (unused categories = 0, low-count categories = 0), and
#> thresholds were ordered. Step/threshold summary: 3 step(s); estimate range = -1.30 to 1.35
#> logits; no disordered steps.
#>
#> Facet measures.
#> Person measures ranged from -2.02 to 2.33 logits (M = 0.03, SD = 1.01). Rater measures
#> ranged from -0.32 to 0.33 logits (M = -0.00, SD = 0.31). Criterion measures ranged from
#> -0.41 to 0.24 logits (M = 0.00, SD = 0.28).

#> Fit and precision.
#> Overall fit was acceptable (infit MnSq = 0.99, outfit MnSq = 1.00). 1 of 56 elements
#> exceeded the 0.5-1.5 fit range. Largest misfit signals: Person:P023 (|metric| = 2.09);
#> Criterion:Organization (|metric| = 1.69); Person:P018 (|metric| = 1.45). Criterion
#> reliability = 0.91 (separation = 3.21). Person reliability = 0.90 (separation = 3.06).
#> Rater reliability = 0.93 (separation = 3.51). For Rater, exact agreement = 0.36, expected
#> exact agreement = 0.37, adjacent agreement = 0.83.
#>
#> Residual structure.
#> Exploratory residual PCA (overall standardized residual matrix) showed PC1 eigenvalue =
#> 2.10 (13.2% variance), with PC2 eigenvalue = 1.79. Facet-specific exploratory residual PCA
#> showed the largest first-component signal in Rater (eigenvalue = 1.55, 38.7% variance).
#> Heuristic reference bands: EV >= 1.4 (critical minimum), >= 1.5 (caution), >= 2.0 (common),
#> >= 3.0 (strong); variance >= 5% (minor), >= 10% (caution), >= 20% (strong).apa$section_map[, c("SectionId", "Heading", "Available")]

blocks are available.Use apa_table() when you want reproducible handoff
tables without rebuilding captions or notes by hand.
