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.
