About this eTextbook

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.

Refunds

A digital file cannot be posted back, so there is no return process. There are situations that are refundable and situations that are not, and both are stated plainly.

Refunded in full, within 30 days of the order:

The file is corrupt, truncated, or will not open in a reader that supports its format.
Content is missing from the edition you were sold.
The wrong title was delivered.
The edition, eText ISBN, author or format does not match this page.
You were charged twice for the same title.
Nothing was delivered and we cannot reissue it.

Not downloaded yet? Cancel within 14 days for a full refund, no reason needed.

Not refundable: a title you downloaded and then decided you did not want, a file that does not suit your device where we did not say it would, buying the wrong edition when this page stated it correctly, and publisher printing or copy limits.

Approved refunds are issued within 2 to 5 business days to the card that paid. Full detail on the Returns & Refund Policy.
