While this entails easy interpretation of the estimated regression effects, it may often lead to incomplete analyses when more complex relationships are indeed present and also bears the risk of false conclusions about the significance/importance of covariates. We will therefore give an overview on extended types of regression models that allows us to go beyond mean regression. More specifically, we will consider generalized additive models for location, scale and shape as well as semiparametric quantile and expectile regression. We will review the basic properties of all three approaches and compare them with respect to the flexibility in terms of the supported types of predictor specification, the availability of software and the support for different types of inferential procedures. The considered model classes are illustrated using a data set on rents for flats in the City of Munich.

Wiese, C. H. R.; Bartels, U. E.; Ruppert, D.; Marung, H.; Luiz, T.; Graf, B. M.; Hanekop, G. G. Palliative care medical emergencies as a consequence of advanced cancer account for approximately 3% of all prehospital emergency cases. Therefore, prehospital emergency physicians (EP) are confronted with ‘end of life decisions’. No educational content exists concerning palliative medicine in emergency medicine curricula. Over the course of 6 months, we interviewed 150 EPs about their experiences in ‘end of life decisions’ using a specific questionnaire. The total response rate was 69% (n = 104). Most of the interviewed EPs (89%, n = 93) had been confronted with palliative care medical emergencies and expressed uncertainties in dealing with these difficult situations, especially in the area of psychosocial care of the patients (50%). The emergency treatment of palliative care patients can become a particular challenge for any EP. A large percentage of interviewed EPs felt uncertain about aspects of social care and in the assessment of decisions at the end of life. Further information and training are necessary to amenable EPs to provide adequate patient-oriented care to palliative care patients and their relatives in emergency situations.

Beside the well-known families, we explicitly describe two new classes of exactly solvable Schrödinger equations that can be reduced to the Hermite equation.

In A. meniscum, a bowl-shaped sponge with a massive skeleton of octactins, the ontogenetically youngest and still uncemented spicules are found at the upper, concave surface, particularly close to the edge. Towards the bottom, the spicules soon become altered through epitaxic cementation and recrystallization. From this skeletal architecture can be inferred that the soft tissues occupied only the uppermost portions of the basal skeleton. The skeletal structure is in many respects similar to that of the recent Petrobiona massiliana, although the ecological adaptations of the two species are fundamentally different.; Astraeospongium bildet ein sekundäres kalkiges Basalskelett und kann somit der morphologischen Gruppierung "koralline Spongien" zugerechnet werden. In A. meniscum, ein schüsseIförmiger Schwamm mit einem massiven Skelett aus Octactinen, befinden sich die ontogenetisch jüngsten und noch unzementierten Spicula an der oberen, konkaven Seite, insbesondere nahe dem Rand. Zum Basis hin ändern sich bald die Spicula durch epitaktische Zementation und Rekristallisation. Aufgrund dieser Skelettarchitektur kann geschlossen werden, daß sich der Weichkörper nur in den obersten Bereichen des Skeletts befand. Die Skelettstruktur ist der der rezenten Petrobiona massiliana in vielerlei Hinsicht ähnlich, wenngleich sich die ökologischen Anpassungen der beiden Arten grundlegend unterscheidet.
