We provide a new definition of breakdown in finite samples with an extension to asymptotic breakdown. Previous definitions center around defining a critical region for either the parameter or the objective function. If for a particular outlier constellation the critical region is entered,...

High-quality short-term forecasts of wind speed are vital to making wind power amore reliable energy source. Gneiting et al. (2006) have introduced a model for the averagewind speed two hours ahead based on both spatial and temporal information. Theforecasts produced by this model are accurate,...

This dissertation is composed of four articles describing inference and visualization of periodic sequences.In the first article, a nonparametric method is proposed for estimating the period and values of a periodic sequence when the data are evenly spaced in time. Theperiod is estimated by a...
