Boosting-Techniken zur Modellierung itemmodifizierender Effekte: Eine Erweiterung klassischer Item-Response-Modelle

$30.00

Eine Erweiterung klassischer Item-Response-Modelle Moritz Berger beschäftigt sich mit einer Erweiterung des klassischen binären Rasch-Modells, mit der es möglich ist, Unterschiede zwischen Personen aus unterschiedlichen Subgruppen bei der Beantwortung von Testitems zu berücksichtigen. Das binäre Rasch-Modell findet Anwendung in der Psychometrie bei der Auswertung von Intelligenztests. Grundannahme dieses Modells ist, dass die Schwierigkeit eines Testitems für alle Personen mit derselben Fähigkeit exakt gleich ist, was jedoch oftmals nicht der Fall ist. Das vorgestellte, erweiterte Modell wird mithilfe von Boosting-Verfahren geschätzt. Auf Basis von Simulationen und echten Datenbeispielen wird die Güte der Modelle und des Schätzverfahrens gründlich untersucht und Grenzen der Methoden aufgezeigt. Boosting-Techniken zur Modellierung itemmodifizierender Effekte: Eine Erweiterung klassischer Item-Response-Modelle is written by Moritz Berger and published by Springer Spektrum. ISBNs for Boosting-Techniken zur Modellierung itemmodifizierender Effekte are 9783658087050, 3658087056 and the print ISBNs are 9783658087043, 3658087048.
