Indices follow Curran (2016) ; person fit in item response theory (the standardized log-likelihood) is optional, and cut-offs can be taken from a reference group. Results are returned per person, with flags, frequency tables of response patterns and plots. Whole batches of data (a second collection phase, one classroom) can be compared with a reference group: the item correlation structure, with permutation tests that leave out flat responders and match the response level, and the Jennrich (1970) test; the similarity of consecutive rows; and near-duplicate respondents. Flagged respondents can be removed in one step and the same confirmatory or exploratory factor model can be refitted with and without them.' authors: - family-names: Ventura-Leon given-names: Jose email: jventuraleon@gmail.com orcid: https://orcid.org/0000-0003-2996-4244 repository: https://cran.r-universe.dev commit: 2fb4cb6b8d3ce217afd195326b5cce0d1eb57777 date-released: '2026-11-08' contact: - family-names: Ventura-Leon given-names: Jose email: jventuraleon@gmail.com orcid: https://orcid.org/0000-0003-2996-4244
