Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Both models had the same degrees of freedom and identical global model fit, showing empirical fit cannot decide between the approaches. → Köhler 2021

q2 · i? · theoretical · r3

Fit comparison of the two DESI multilevel latent variable models. The article reports identical fit (χ2 = 715.5; df = 226; RMSEA = 0.014; CFI = 0.963; TLI = 0.960) and concludes "the empirical model fit is no criterion for model selection".

"Both models have the same number of degrees of freedom and an identical global model fit (χ2 = 715.5; df = 226; RMSEA = 0.014; CFI = 0.963; TLI = 0.960). This illustrates that both models can be transformed into another, and the empirical model fit is no criterion for model selection."
