Reduce Redundancy via Iterative UVA (with Redundant Pair Logging)

Source: R/pipeline_helpers_optimized.R
reduce_redundancy_uva.Rd

Applies EGAnet::UVA iteratively and logs human-readable redundant item sets.

Usage

reduce_redundancy_uva(
  embedding_matrix,
  items,
  corr = "auto",
  uva.cut.off = 0.2
)

Arguments

embedding_matrix

A numeric matrix of embeddings (columns = items).

items

Data frame with ID and statement columns.

corr

Character. Correlation method to use. Default "auto" uses EGAnet's automatic correlation detection. Other options: "pearson", "spearman", "cosine".

uva.cut.off

Numeric in [0, 1). The weighted topological overlap threshold passed to EGAnet::UVA. Items with pairwise wTO at or above this value are flagged as redundant. Default 0.20.

Value

A list with the reduced matrix, sweep metadata, human-readable redundancy groups, and removal_log, a tidy item-level table containing removed IDs, retained redundant partners, and wTO statistics.
