Fit a multiblock psychometric/gaze/pupil/quality structure map — fit_multiblock_process

Uses FactoMineR MFA when available/requested. A block-standardized PCA fallback is available as a transparent exploratory reference and is explicitly labeled.

Usage

fit_multiblock_process_map(
  x,
  blocks = NULL,
  id = NULL,
  engine = c("auto", "FactoMineR", "pca_block_scaled"),
  ncp = 5L
)

Arguments

x: A `process_feature_blocks()` object or data frame.
blocks: Required if `x` is a data frame.
id: Optional identifier.
engine: `auto`, `FactoMineR`, or `pca_block_scaled`.
ncp: Number of components retained where supported.

Value

An object of class "eye_multiblock_process_map", stored as a named list, with components "model", "person_coordinates", "variable_coordinates", "block_coordinates", "blocks", "engine", "status", "caveat". It contains a multiblock psychometric/gaze/pupil/quality structure map and associated metadata or diagnostics needed to interpret the result.
