Loadings-based Factor-Retention Criteria and Some (New) Alternatives

It seems to me that while q-specific, Humphrey’s rule and the >2 sig. factor rule are problematic to decide on the number of retained factors, because they depend on loadings, which are available only later in the procedure and dependent on the rotation method. Instead, I suggest an additional q-specific approach, based on changes in communalities and residual correlation matrices between factor models in question. Read More
