Description: Integrates large language model generated item responses into
    psychometric calibration studies through a mixed-subjects design for
    unidimensional two-parameter and one-parameter logistic item response
    theory models. Human pilot responses are augmented with model-generated
    responses using a prediction-powered inference estimator (Angelopoulos,
    Bates, Fannjiang, Jordan and Zrnic (2023) <doi:10.1126/science.adi6000>;
    Angelopoulos, Duchi and Zrnic (2023) <doi:10.48550/arXiv.2311.01453>)
    adapted to marginal maximum-likelihood estimation, following the
    mixed-subjects design of Broska, Howes and van Loon (2025)
    <doi:10.1177/00491241251326865>. The estimator is anchored to the human
    responses and is asymptotically unbiased for the human item parameters at
    any tuning weight; the weight on the synthetic responses is chosen to
    minimize propagated ability-score risk, down-weighting uninformative or
    biased generated responses. Louis-corrected sandwich standard errors,
    ability scoring, cross-fitted tuning, and scale linking are also provided.
