Considered in the framework of linear regression analysis, basic tau equivalence means a slope of zero across the set of factor loadings, but without their restriction to exact correspondence. Allowing for deviations from correspondence enables the account of item particularities, whereas a zero slope keeps away systematic influences unrelated to the attribute of interest. This measurement model is illustrated using an example matrix and data from two simulation studies. The fit results of the two described methods for realizing basic tau equivalence are highly correlated.<\/jats:p>","DOI":"10.3389\/fams.2026.1778863","type":"journal-article","created":{"date-parts":[[2026,3,9]],"date-time":"2026-03-09T05:23:01Z","timestamp":1773033781000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Basically
