Der Beitrag zeigt, in welchem Schritt der Analyse von großen Datenmengen die Behandlung von fehlenden Daten stattfindet und warum ein angemessener Umgang mit diesen unerlässlich ist. Vorgestellt werden zudem Methoden zum Umgang mit fehlenden Werten, die sich insbesondere im Kontext von...

We develop a method for directly modeling cointegrated multivariate time series that are observed in mixed frequencies. We regard lower-frequency data as regularly (or irregularly) missing and treat them with higher-frequency data by adopting a state-space model. This utilizes the structure of...

In this paper we derive nonparametric bounds for the cumulative incidence curve within a competing risks model with partly identified interval data. As an advantage over earlier attempts our approach also gives valid results in case of dependent competing risks. We apply our framework to...
