In autoFC: Automatic Toolkit for Construction, Optimization, Scoring and Simulation of Forced-Choice Tests

Generate Stan Syntax and Data for TIRT Models

Description

Automatically reduces logical dependencies for full rank data (Heister et al. 2025), handles missing/MOLE data natively, and generates Stan syntax capable of within-chain parallelization (reduce_sum).

Usage

generate_tirt_stan_syntax(
  pairwise_data,
  n_blocks,
  block_size,
  n_traits,
  key_matrix,
  trait_col,
  key_col,
  apply_heister = TRUE
)

Arguments

pairwise_data	Dataframe of binary outcomes.
n_blocks	Integer. Number of blocks.
block_size	Integer. Number of items per block.
n_traits	Integer. Number of traits.
key_matrix	A data.frame indicating item trait and item sign.
trait_col	Character string. The name of the column in key_matrix indicating the trait measured by the item.
key_col	Character string. The name of the column in key_matrix indicating the keying direction of the item (e.g., positive/negative).
apply_heister	Logical. Apply logical dependency reduction? Defaults to TRUE.

Value

A list containing syntax (Stan code) and data (List for rstan).
