Bayesiansk itemanalyse

Bayesiansk itemanalyse anvender Bayesiansk inferens til at estimere statistik på itemniveau – sværhedsgrad, diskrimination og distraktoreffektivitet – ved at kombinere observerede svardata med forudgående viden. Den producerer fulde posterior-fordelinger over itemparametre snarere end enkelte punkt-estimater, hvilket giver rigere usikkerhedsinformation, især med små stikprøver.
