Various outputs from SPSS (version 27) FACTOR for the IDS-2 (Grob & Hagmann-von Arx, 2018), the WJIV (3 to 5 and 20 to 39 years; McGrew, LaForte, & Schrank, 2014), the DOSPERT (Frey et al., 2017; Weber, Blais, & Betz, 2002), and four simulated datasets (baseline, case_1a, case_6b, and case_11b, see test_models and population_models) used in Grieder and Steiner (2022).
SPSS_27A list of 8 containing EFA results for each of the data sets mentioned above. Each of these eight entries is a list of 4, of the following structure:
(matrix) - F1 to FN = unrotated factor loadings obtained with the FACTOR algorithm with PAF. Rownames are the abbreviated subtest or item names, and generic variable labels (V1 to VN) for the simulated datasets.
(matrix) - F1 to FN = varimax rotated factor loadings obtained with the FACTOR algorithm with PAF. Rownames are the abbreviated subtest or item names, and generic variable labels (V1 to VN) for the simulated datasets.
(matrix) - F1 to FN = promax rotated factor loadings obtained with the FACTOR algorithm with PAF. Rownames are the abbreviated subtest or item names, and generic variable labels (V1 to VN) for the simulated datasets.
(matrix) - F1 to FN = intercorrelations of the promax rotated loadings.
The principal axis factoring was run with the iteration limit raised above
SPSS's own default of 25, so reproducing these solutions requires the same: case_1a
needs 60 iterations and case_11b needs 33, and at max_iter = 25 both stop short of
convergence and differ from the stored loadings in the second decimal. Use
estimate_control(type = "SPSS", max_iter = 500) when checking a preset against these
references; the other two simulated cases converge in six iterations and are
unaffected.
