Robust statistical procedures for location and scale dynamic models with applications to risk management

Mancini, Loriano ; Ronchetti, Elvezio (Dir.) ; Trojani, Fabio (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2004 ; 2004ECO001.

In the first part of the thesis, we study the local robustness of inference procedures of the conditional location and scale parameters in a stationary time series model. We first derive optimal bounded-influence estimators for the parameters of conditional location and scale models under a conditionally Gaussian reference model. Based on these results, optimal bounded-influence versions of the...

Evolution in invasive plants: implications for biological control

Müller-Schärer, Heinz ; Schaffner, Urs ; Steinger, Thomas

In: Trends in Ecology and Evolution, 2004, vol. 19, p. 417-422

Evidence is increasing that invasive plants can undergo rapid adaptive evolution during the process of range expansion. Here, we argue that evolutionary change during invasions will also affect plant–antagonist inter-actions and, thus, will have important implications for biological control programmes targeted at invasive plants. We explore how altered selection in the new range might influence...

Due to the growing importance of services in economic development, there is an impressive body of knowledge on the process of internationalization and service industries. The last comprehensive academic study on internationalization and the hotel industry was undertaken at the beginning of the...
