"Improving the Rank-Adjusted Anderson-Rubin Test with Many Instruments and Persistent Heteroscedasticity"
No full textAnderson and Kunitomo (2007) have developed the likelihood ratio criterion, which is called the Rank-Adjusted Anderson-Rubin (RAAR) test, for testing the coefficients of a structural equation in a system of simultaneous equations in econometrics against the alternative hypothesis that the equation of interest is identified. It is related to the statistic originally proposed by Anderson and Rubin (1949, 1950), and also to the test procedures by Kleibergen (2002) and Moreira (2003). We propose a modified procedure of RAAR test, which is suitable for the cases when there are many instruments and the disturbances have persistent heteroscedasticities.
LABORSYSTEM RUBIN / FELDSYSTEM RUBIN
No full textIm Rahmen des Projekts "Laborsystem RUBIN" (Rechner-Unterstütztes BerufsINformationssystem) wurde ein Konzept für Laieninformationssysteme entworfen. Dieses wurde am Beispiel "Berufsinformation für Berufswähler" in verschiedenen Varianten implementiert. Informationen zu Berufen können hier in Form von Texten, Standbildern und Filmen abgerufen werden. In Benutzeruntersuchungen wurde geklärt, wieweit sich die einzelnen Varianten bewähren. Im Folgeprojekt Feldsystem RUBIN wurde untersucht, in welchem Ausmaß sich ein System vom Typ RUBIN unter praxisnahen Anwendungsbedingungen im Vergleich zu einer bestehenden Selbstinformationseinrichtung bewährt, die den Zugriff auf ein vergleichbares Informationsangebot auf herkömmliche Weise ermöglicht. Im vorliegenden Artikel werden Ziele, Vorgehen und Ergebnisse beider Projekte in Ausschnitten skizziert
Movable Type [installation]
No full textCentral corridor of lobby showing two grids of seven rows and 40 columns each on opposing walls; Moveable Type, by New York artist Ben Rubin and UCLA associate professor (in statistics) Mark Hansen, is an artwork commissioned for the ground-floor lobby of The New York Times Building in New York City. It is a dynamic portrait of The Times. Statistical methods and natural-language processing algorithms are used to parse the daily output of the paper (news, features, editorials) and the archives, as well as the activity of visitors to the NYTimes.com website (browsing, searching, commenting). The resulting refracted view of The Times is displayed on 560 vacuum-fluorescent display screens installed in the lobby. Each screen is 4 1/4 inches tall and 8 1/2 inches long. Their resolution is 128 x 256 pixels. The design was coordinated with the architects, Renzo Piano Building Workshop.

Robert H. Rubin and infectious disease in transplantation
No full textRobert H. Rubin, M.D. was among the first physician-scientists to focus attention on the infectious diseases associated with immune suppression. A superb bedside clinician and teacher, he developed many of the concepts central to the care and improved survival of organ transplant and stem cell transplant recipients. These concepts have provided the basis of clinical investigation and basic research for multiple generations of infectious disease specialists, immunologists, and transplant surgeons
