build_apa_outputs: Build APA text outputs from model results

In mfrmr: Estimation and Diagnostics for Many-Facet Measurement Models

Build APA text outputs from model results

Description

Build APA text outputs from model results

Usage

build_apa_outputs(
  fit,
  diagnostics,
  bias_results = NULL,
  context = list(),
  whexact = FALSE
)

Arguments

fit	Output from fit_mfrm().
diagnostics	Output from diagnose_mfrm().
bias_results	Optional output from estimate_bias().
context	Optional named list for report context.
whexact	Use exact ZSTD transformation.

Details

context is an optional named list for narrative customization. Frequently used fields include:

• assessment, setting, scale_desc

• rater_training, raters_per_response

• rater_facet (used for targeted reliability note text)

• line_width (optional text wrapping width for report_text; default = 92)

Output text includes residual-PCA screening commentary if PCA diagnostics are available in diagnostics.

For bounded GPCM, this helper returns a caveated partial reporting bundle over supported diagnostics, direct tables, and plots. It also includes a gpcm_boundary table. Treat the output as slope-aware sensitivity-reporting text, not FACETS score-side equivalence, automatic operational scoring, or design-forecasting evidence.

By default, report_text includes:

• model/data design summary (N, facet counts, scale range)

• optimization/convergence metrics (Converged, Iterations, LogLik, AIC, BIC)

• anchor/constraint summary (noncenter_facet, anchored levels, group anchors, dummy facets)

• latent-regression population-model wording when fit has an active population_formula

• category/threshold diagnostics (including disordered-step details when present)

• overall fit, misfit count, and top misfit levels

• facet reliability/separation, residual PCA summary, and bias-screen counts

Value

An object of class mfrm_apa_outputs with:

• report_text: APA-style Method/Results draft prose

• table_figure_notes: consolidated draft notes for tables/visuals

• table_figure_captions: draft caption candidates without figure numbering

• section_map: package-native section table for manuscript assembly

• contract: structured APA reporting contract used for downstream checks

Interpreting output

• report_text: manuscript-draft narrative covering Method (model specification, estimation, convergence) and Results (global fit, facet separation/reliability, misfit triage, category diagnostics, residual-PCA screening, bias screening). Written in third-person past tense following APA 7th edition conventions, but still intended for human review.

• table_figure_notes: reusable draft note blocks for table/figure appendices.

• table_figure_captions: draft caption candidates aligned to generated outputs.

• active latent-regression fits add a population-model section and Table 5 notes/captions that distinguish conditional-normal coefficient reporting from post hoc regression on EAP/MLE scores.

When bias results or PCA diagnostics are not supplied, those sections are omitted from the narrative rather than producing placeholder text.

Typical workflow

1. Build diagnostics (and optional bias results). For RSM / PCM reporting runs, prefer an MML fit and diagnose_mfrm(..., diagnostic_mode = "both").

2. Run build_apa_outputs(...).

3. Check summary(apa) for completeness.

4. Insert apa$report_text and note/caption fields into manuscript drafts after checking the listed cautions.

Context template

A minimal context list can include fields such as:

• assessment: name of the assessment task

• setting: administration context

• scale_desc: short description of the score scale

• rater_facet: rater facet label used in narrative reliability text

Input validation

fit must be an mfrm_fit object from fit_mfrm(). diagnostics must be an mfrm_diagnostics object from diagnose_mfrm(). context must be a list (use NULL or list() for no extra context). If supplied, bias_results must come from estimate_bias() or another package-native bias helper that provides a table component.

Examples

# Fast smoke run: a JML fit and a legacy diagnostic let us build the
# APA bundle and confirm `report_text` is non-empty in well under
# a second.
toy <- load_mfrmr_data("example_core")
fit_quick <- fit_mfrm(toy, "Person", c("Rater", "Criterion"), "Score",
                      method = "JML", maxit = 30)
diag_quick <- diagnose_mfrm(fit_quick, residual_pca = "none",
                             diagnostic_mode = "legacy")
apa_quick <- build_apa_outputs(fit_quick, diag_quick)
nchar(apa_quick$report_text) > 0


fit <- fit_mfrm(toy, "Person", c("Rater", "Criterion"), "Score",
                method = "MML", quad_points = 7, maxit = 30)
diag <- diagnose_mfrm(fit, residual_pca = "both", diagnostic_mode = "both")
apa <- build_apa_outputs(

)
s_apa <- summary(apa)
s_apa$overview
# Look for: `SentenceCount` non-zero in every section that the run
#   should support (Method / Results / fit / reliability / bias).
#   Zero counts mean that section's prose is empty and the
#   manuscript will need to fill it manually.
chk <- reporting_checklist(fit, diagnostics = diag)
head(chk$checklist[, c("Section", "Item", "DraftReady", "NextAction")])
# Look for: rows with `DraftReady = "yes"` are ready to paste into
#   the manuscript. `"no"` rows tell you which helper / setting
#   needs to run before that paragraph can be drafted, via
#   `NextAction`. Aim for every Visual Displays / Reliability /
#   Diagnostics row to be `"yes"` before submitting.
cat(apa$report_text)
apa$section_map[, c("SectionId", "Available")]
