摘要:

Data editing and imputation are important activities in the processing of survey data. Several of their computational aspects are discussed. The logical structure of a questionnaire, as defined in Willenborg (1988), is the key structure considered in this paper. It is used as a starting point to describe these activities. The present paper is a continuation of Willenborg (1995).

摘要:

We give a new proof of the asymptotic normality of a class of linear functionals of the nonparametric maximum likelihood estimator (NPMLE) of a distribution function with “case 1” interval censored data. In particular our proof simplifies the proof of asymptotic normality of the mean given in Groeneboom and Wellner (1992). The proof relies strongly on a rate of convergence result due to van de Geer (1993), and methods from empirical process the

摘要:

A very well‐known model in software reliability theory is that of Littlewood (1980). The (three) parameters in this model are usually estimated by means of the maximum likelihood method. The system of likelihood equations can have more than one solution. Only one of them will be consistent, however. In this paper we present a different, more analytical approach, exploiting the mathematical properties of the log‐likelihood function itself. Our belief is that the ideas and methods developed in this paper could also be of interest for statisticians working on the estimation of the parameters of the generalised Pareto distribution. For those more generally interested in maximum likelihood the paper provides a ‘practical case’, indicating how complex matters may become when only three parameters are involved. Moreover, readers not familiar with counting process theory and software reliability are given a first intro

摘要:

This article attempts to provide a formal framework for a data based inference which explicitly and consistently recognizes the approximate nature of probability models. It is based on the idea that a stochastic model is adequate if samples generated under the model are very much like the sample actually obtained. The formalization is based on the concept of data feature. Examples are given of applying the ideas to different areas of statistics including location‐scale models, densities, non‐parametric regression, interlaboratory test, auto‐regressive processes and the analysis of variance. The four cornerstones of the approach are direct comparison, approximation, weak topologies and parsimony. The approach is contrasted to that of much of conventional statistics many of whose concepts are pathologically discontinuous with respect to the topology of data analysis and common

摘要:

Statistica Neerlandica encourages the reporting on theses in probability, statistics, biometrics, econometrics, and operations research, submitted to Dutch universities. The main purpose of this section is to inform the reader briefly of the nature, the practical and theoretical importance, the methods used, and the results presented in recent theses. It is understood that contributions to this section meet with the approval of the supervisor(s) of the thesis.Notes (not exceeding 300 words) should be sent to the column editor.
