  "Description": "In Latent Space Item Response Models, subjects and items\nare embedded in a multidimensional Euclidean latent space. As\nsuch, interactions among persons, items, and person-item\ncombinations can be revealed that are unmodelled in more\nconventional item response theory models. This package\nimplements the methods from Molenaar & Jeon\n(2026)<doi:10.1017/psy.2025.10068> and can be used to fit\nLatent Space Item Response Models to data using joint maximum\nlikelihood estimation. The package can handle binary data,\nordinal data, and data with mixed scales. The package\nincorporates facilities for data simulation, rotation of the\nlatent space, and K-fold cross-validation to select the number\nof dimensions of the latent space.",
