Nonsingular subsampling for S-estimators with categorical predictors
Nonsingular subsampling S-estimators categorical predictors
2012/9/18
An integral part of many algorithms for S-estimators of linear regression is random subsam-pling. For problems with only continuous predictors simplerandom subsampling is a reliable method to generate...
This note introduces the method of cross-conformal prediction, which is a hybrid of the methods of inductive conformal prediction and cross-validation, and studies its validity and predictive eciency...
Some results on random design regression with long memory errors and predictors
memory errors predictors random design
2011/3/24
This paper studies nonparametric regression with long memory (LRD) errors and predictors. First, we formulate general conditions which guarantee the standard rate of convergence for a nonparametric ke...
Predictors of short-term decay of cell phone contacts in a large scale communication network

2011/3/25
Under what conditions is an edge present in a social network at time t likely to decay or persist by some future time t + Delta(t)? Previous research addressing this issue suggests that the network ra...

Kink estimation in stochastic regression with dependent errors and predictors
Change point Kink High-order kernel Zero-crossing technique Long-range dependence Random Design Separationrate lemma
2010/3/11
In this article we study the estimation of the location of jump
points in the first derivative (referred to as kinks) of a regression function
μ in two random design models with different long-range...

job satisfaction Norwegian hospitals micro unit culture
2009/9/28
The professional values of medicine, the organizational and holistic skills of nurses and the practical experience of auxiliaries should all be valued in the building of interdependent micro teams.
INFORMATION INEQUALITIES FOR THE BAUES RISK OF PREDICTORS
Prediction Bayes risk information inequality
2009/9/18
The paper provides several lower bounds and an upper
bound for the Bayes risk in statistical prediction theory. The bounds
depend on the Fisher information or the bias of the Bayes predictor.
The r...
