Asymptotics for posterior hazards [PDF]
An important issue in survival analysis is the investigation and the modeling of hazard rates. Within a Bayesian nonparametric framework, a natural and popular approach is to model hazard rates as kernel mixtures with respect to a completely random ...

Searching for a trail of evidence in a maze
, 2007 Consider a graph with a set of vertices and oriented edges connecting pairs of vertices. Each vertex is associated with a random variable and these are assumed to be independent.

Overall Specialization and Income: Countries Diversity [PDF]
This paper gives evidence to a stylized fact often disregarded in international trade empir- ics: countries' diversification. In the last fifteen years, the growth of world trade coexisted with the tendency of countries to reduce the specialization

Nonparametric approach for structural dynamics of high-voltage cables
Results in EngineeringHigh-voltage cables, as applied in the electro-mobility, are highly complex structures regarding their vibration behaviour. The high complexity leads to considerable uncertainty in models for a finite element method (FEM) simulation, which is shown, for ...

Detection of an anomalous cluster in a network
, 2010 We consider the problem of detecting whether or not, in a given sensor network, there is a cluster of sensors which exhibit an "unusual behavior." Formally, suppose we are given a set of nodes and attach a random variable to each node.

Nonparametric Feature Extraction from Dendrograms
, 2019 We propose feature extraction from dendrograms in a nonparametric way. The Minimax distance measures correspond to building a dendrogram with single linkage criterion, with defining specific forms of a level function and a distance function over that ...
