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? Item and response missing data characterized as MCAR for linear tests have no differential effects on model fit across Designs 1 to 4, so linear-test constructs recover reasonably well at the item level. → Shudong Wang 2012

q2 · i? · causal · r2

Simulation results (Tables 7 and 8) comparing model fit across Designs 1-4, which vary MCAR item and response missingness; the article reports "Both unidimensional models (Rasch and 2PL) fit data well" while the bifactor model recovered data poorly.

"First, at the item level, results show that both item and response missing data characterized as MCAR for linear tests have no differential effects on models fit across Designs 1 to 4. Both unidimensional models (Rasch and 2PL) fit data well but the multidimensional model (bifactor model) recoveres data poorly."
