Embeds item text with\nsentence transformers or other language models, transforms the\nembeddings into item-by-item similarity matrices, and extracts\nlatent factor structure via standard exploratory factor\nanalysis. Supports embedding-adapted parallel analysis, several\nsimilarity transforms (atomic reversed, SQuID centering,\nmean-centered Pearson), and fit diagnostics tailored to\nembedding matrices (TEFI, RMSR, CAF, McDonald's omega).
