fit_manyfacet_process_irt: Many-facet process IRT reference model

In eyeprocess: Harmonize Eye-Tracking, Pupillometry, Biometrics, and Psychometric Process Data

Many-facet process IRT reference model

Description

Fits crossed random effects for available person, item, device, session, site, algorithm, and AOI-definition facets. For a binary response this is a generalized many-facet reference model; it is not marketed as a FACETS software replica.

Usage

fit_manyfacet_process_irt(
  data,
  response = "response",
  process = NULL,
  person = "participant_id",
  item = "item_id",
  device = NULL,
  session = NULL,
  site = NULL,
  algorithm = NULL,
  aoi_definition = NULL,
  process_family = c("gaussian", "poisson", "negative_binomial")
)

Arguments

data	Input data frame or compatible tabular object.
response	Response variable or response-column name.
process	Process variable or column name.
person	Person or participant identifier column.
item	Item identifier, name, or item column.
device	Device identifier or device facet.
session	Session identifier or session facet.
site	Site identifier or site facet.
algorithm	Algorithm identifier or algorithm facet.
aoi_definition	Value supplied to 'aoi_definition'; see Details for its model-specific role.
process_family	Distributional family for the process channel.

Value

An object of class "eye_manyfacet_process_irt", stored as a named list, with components "response_model", "process_model", "facets", "process_family", "status". It contains many-facet process IRT reference model and associated metadata or diagnostics needed to interpret the result.
