 Abstract:
 ... For computing the exact value of the halfspace depth of a point w.r.t. a data cloud of n points in arbitrary dimension, a theoretical framework is suggested. Based on this framework a whole class of algorithms can be derived. In all of these algorithms the depth is calculated as the minimum over a finite number of depth values w.r.t. proper projections of the data cloud. Three variants of this cla ...

 Abstract:
 ... In this paper, we propose an optimization algorithm called the modified local quadratic approximation algorithm for minimizing various ℓ1penalized convex loss functions. The proposed algorithm iteratively solves ℓ1penalized local quadratic approximations of the loss function, and then modifies the solution whenever it fails to decrease the original ℓ1penalized loss function. As an extension, we ...

 Abstract:
 ... Among the measures of a distribution’s location, the mode is probably the least often used, although it has some appealing properties. Estimators for the mode of univariate distributions are widely available. However, few contributions can be found for the multivariate case. A consistent direct multivariate mode estimation procedure, called minimum volume peeling, can be outlined as follows. The a ...

 Abstract:
 ... In this article, we propose a new estimation procedure for a class of semiparametric mixture models that is a mixture of unknown locationshifted symmetric distributions. The proposed method assumes that the nonparametric symmetric distribution falls in a rich class of continuous normal scale mixture distributions. With this new modeling approach, we can suitably avoid the misspecification problem ...

 Abstract:
 ... A novel method is presented for fast convolution of a pair of probability mass functions defined on a finite lattice with guaranteed accuracy of all computed values. This method, called aFFTC (accurate FFT convolution), utilizes the Fast Fourier Transform (FFT) for the gain in speed, but relying on a rigorous analysis of the propagation of roundoff error, it can detect and circumvent the accumula ...

 Abstract:
 ... Experiments in the field of behavioral economics often require repeated matching of participants to groups over multiple periods. Perfect stranger matching requires that no two participants interact more than once during the experiment. Computing a sequence of perfect stranger matches is an NPhard problem that has received little attention in experimental economics literature beyond bruteforce a ...

 ... We construct minimumwidth confidence bands with a predefined nominal coverage from a finite set of sample paths. In contrast to the several heuristics suggested in the literature, our mixedinteger optimization algorithm calculates global minimumwidth pathwise confidence bands. For very large problems, our solution can be used as an approximation with a bounded and known gap to the globally opti ...

 Abstract:
 ... We consider a situation where a student–school matching has already been temporarily decided, but unexpectedly the quotas of some schools are increased and/or some new schools enter. Furthermore, the school priority orders are allowed to be weak. We provide a polynomialtime algorithm to derive a student optimal stable matching under the profile of increased quotas that Pareto dominates the stable ...

This opinion article explores how sustained neural firing in association areas allows highorder mental representations to be coactivated over multiple perceptionaction cycles, permitting sequential mental states to share overlapping content and thus be recursively interrelated. The term “statespanning coactivity” (SSC) is introduced to refer to neural nodes that remain coactive as a group over ...

 Abstract:
 ... Most gene prediction methods detect coding sequences from transcriptome assemblies in the absence of closely related reference genomes. Such methods are of limited application due to high transcript fragmentation and extensive assembly errors, which may lead to redundant or false coding sequence predictions. We present inGAPCDG, which can construct fulllength and nonredundant coding sequences f ...

 ... This article considers sieve estimation in the Cox model with an unknown regression structure based on right‐censored data. We propose a semiparametric pursuit method to simultaneously identify and estimate linear and nonparametric covariate effects based on B‐spline expansions through a penalized group selection method with concave penalties. We show that the estimators of the linear effects and ...

 Abstract:

Penalized likelihood‐based approach is proved to be effective for both variable selection and estimation simultaneously. In the context of a spatially dependent binary variable, an uniquely interpretable likelihood is not available, rather a quasi‐likelihood might be more suitable. We develop ...

Difference spectroscopy between two close systems is widely used to augment its selectivity to the different parts of the observed system, though the molecular dynamics calculation of tiny difference spectra would be computationally extraordinary demanding by subtraction of two spectra. Therefore, we have proposed an efficient computational algorithm of difference spectra without resorting to the ...

The parameters of the proposed algorithm are estimated by the maximum likelihood approach. How ...

 Abstract:
 ... Dispersion regression is often used to predict the expected deviance in a generalised linear model. Using the individual deviance residual as the response variable in that model is considered the standard approach in dispersion modelling. In this paper, we investigate an alternative approach by fitting the dispersion model on the individual Pearson residual responses, which is more straightforward ...

 ... We study the use of randomeffect models for variable selection in highdimensional generalized linear models where the number of covariates exceeds the sample size. Certain distributional assumptions on the random effects produce a penalty that is nonconvex and unbounded at the origin. We introduce a unified algorithm that can be applied to various statistical models including generalized linear ...
