Van Es, B. (author), Jongbloed, G. (author), Van Zuijlen, M. (author)A new nonparametric estimation procedure is introduced for the distribution function in a class of deconvolution problems, where the convolution density has one discontinuity. The estimator is shown to be consistent and its cube root asymptotic distribution theory is established. Known results on the minimax risk for the estimation problem...journal article 1998

Groeneboom, P. (author), Jongbloed, G. (author), Wellner, J.A. (author)We study the two-dimensional process of integrated Brownian motion and Brownian motion, where integrated Brownian motion is conditioned to be positive. The transition density of this process is derived from the asymptotic behavior of hitting times of the unconditioned process. Explicit expressions for the transition density in terms of confluent...journal article 1999

Groeneboom, P. (author), Jongbloed, G. (author), Wellner, J.A. (author)We study nonparametric estimation of convexregression and density functions by methods of least squares (in the regression and density cases) and maximum likelihood (in the density estimation case).We provide characterizations of these estimators, prove that they are consistent and establish their asymptotic distributions at a fixed point of...journal article 2001

Groeneboom, P. (author), Jongbloed, G. (author), Wellner, J.A. (author)A process associated with integrated Brownian motion is introduced that characterizes the limit behavior of nonparametric least squares and maximum likelihood estimators of convex functions and convex densities, respectively. We call this process “the invelope” and show that it is an almost surely uniquely defined function of integrated Brownian...journal article 2001

Jongbloed, G. (author), Van der Meulen, F.H. (author)We consider two nonparametric procedures for estimating a concave distribution function based on data corrupted with additive noise generated by a bounded decreasing density on (0, ?). For the maximum likelihood (ML) estimator and least squares (LS) estimator, we state qualitative properties, prove consistency and propose a computational...journal article 2009

Groeneboom, P. (author), Jongbloed, G. (author), Witte, B.I. (author)We consider the problem of estimating the distribution function, the density and the hazard rate of the (unobservable) event time in the current status model. A well studied and natural nonparametric estimator for the distribution function in this model is the nonparametric maximum likelihood estimator (MLE). We study two alternative methods for...journal article 2010

Roth, M. (author), Buishand, T.A. (author), Jongbloed, G. (author), Klein Tank, A.M.G. (author), Van Zanten, J.H. (author)Regional frequency analysis is often used to reduce the uncertainty in the estimation of distribution parameters and quantiles. In this paper a regional peaks-over-threshold model is introduced that can be used to analyze precipitation extremes in a changing climate. We use a temporally varying threshold, which is determined by quantile...journal article 2012

Roth, M. (author), Buishand, T.A. (author), Jongbloed, G. (author), Klein Tank, A.M.G. (author), Van Zanten, J.H. (author)Projections of extreme precipitation are of great importance, considering the potential severe impacts on society. In this study a recently developed regional, non-stationary peaks-over-threshold approach is applied to two transient simulations of the RACMO2 regional climate model for the period 1950–2100, driven by two different general...journal article 2014

Groeneboom, P. (author), Jongbloed, G. (author)We study nonparametric isotonic confidence intervals for monotone functions. In [Ann. Statist. 29 (2001) 1699–1731], pointwise confidence intervals, based on likelihood ratio tests using the restricted and unrestricted MLE in the current status model, are introduced. We extend the method to the treatment of other models with monotone functions,...journal article 2015

Roth, M. (author), Buishand, T.A. (author), Jongbloed, G. (author)Rainfall extremes are thought to have increased over recent years. Typically linear trends have been considered to describe the temporal evolution of high quantiles of the daily rainfall distribution. For long records it is important to allow more flexibility. Quantile regression methods are available to estimate monotone trends for single...journal article 2015

(author)Traditionally, quantifying climate change induced uncertainty in ecological indicators requires stochastic simulation with a chain of physically-based models describing various processes such as hydrodynamics, waves, sediment transport and ecology. Such Monte Carlo based simulation on the entire model chain, especially with large sample size, is...abstract 2018

Jongbloed, B.C.P. (author), Teuwen, Julie J.E. (author), Palardy, Genevieve (author), Villegas, I.F. (author)Continuous ultrasonic welding (CUW) is an innovative high-speed joining method for thermoplastic composites. Currently, thin flat energy directors (EDs) are used to focus the heat generation at the weld line. The resulting fracture surfaces exhibit large areas of intact ED, resulting in a non-uniform weld, and significantly lowering the strength...conference paper 2018
