Absolute फिट आँकड़ों का अपना अर्थ और सुझाए गए cutoff होते हैं.
Relative फिट आँकड़ों का अर्थ केवल मॉडलों की तुलना में होता है.
आम cutoff मान:
# Run the EFA with six factors (as indicated by your scree plot) EFA_model <- fa(bfi_EFA, nfactors = 6)# View results from the model object EFA_model
The total number of observations was 1400 with Likelihood Chi Square = 618.43 with prob < 1.2e-53Tucker Lewis Index of factoring reliability = 0.916 RMSEA index = 0.045 and the 90 % confidence intervals are 0.041 0.048BIC = -576.87
# Run each theorized EFA on your dataset
bfi_theory <- fa(bfi_EFA, nfactors = 5)
bfi_eigen <- fa(bfi_EFA, nfactors = 6)
# Compare the BIC values bfi_theory$BIC bfi_eigen$BICbfi_theory$BIC bfi_eigen$BIC
