import_tam_fit: Import a 'TAM' fit to an mfrmr-compatible bundle

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

Import a TAM fit to an mfrmr-compatible bundle

Description

Extracts item / step / person parameters from a TAM::tam.mml(), TAM::tam.jml(), or TAM::tam.mml.mfr() fit. The multi-facet tam.mml.mfr() path is detected automatically and each non-person facet is mapped onto a row of fit$facets$others so downstream MFRM helpers (e.g. plot_qc_dashboard()) work on the imported object.

Usage

import_tam_fit(
  fit,
  model = c("RSM", "PCM", "GPCM"),
  item_facet = "Item",
  compute_fit = FALSE
)

Arguments

fit	An object returned by TAM::tam.mml(), TAM::tam.jml(), or TAM::tam.mml.mfr().
model	Same as import_mirt_fit().
item_facet	Name to assign to the item facet for the single-facet path. Ignored when the input is a multi-facet tam.mml.mfr fit (the original facet names are preserved).
compute_fit	Logical. When TRUE, run TAM::tam.fit() and TAM::tam.personfit() to populate Infit / Outfit columns on the returned facet tables, plus build a measurement-side mfrm_diagnostics bundle. Default FALSE.

Value

An mfrm_imported_fit object. Slots mirror import_mirt_fit().
