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."
Discussion¶
Related Claims¶
- In a DESI reanalysis, the ANCOVA approach yielded a non-significant effect of teacher supportiveness on listening comprehension while the CHANGE approach yielded a larger, significant effect — related
- The ESDM's unidirectional trait-ACH-to-trait-ASC path is not empirically identified, and the confounder-based RI-LTVC alternative shows poor fit with no support for a time-varying confounder — possibly the same claim (merge candidate)
- Global-fit evidence does not clearly favor unidimensional over multidimensional academic resilience measurement models, as fit-index pass rates diverge by index — related
- The cross-lagged model holds equally for intervention and control groups and for boys and girls — related
