Abstract
Nonnormality of data presents unique challenges for researchers who wish to carry out structural equation modeling. The subsequent SPSS syntax program computes bootstrap-adjusted fit indices (comparative fit index, Tucker–Lewis index, incremental fit index, and root mean square error of approximation) that adjust for nonnormality, along with the Bollen–Stine bootstrap-adjusted 2 equivalent statistic and associated scaling factor.
