1. Bayesian Cluster Analysis : Some Extensions to Non-standard Situations
Sammanfattning : The Bayesian approach to cluster analysis is presented. We assume that all data stem from a finite mixture model, where each component corresponds to one cluster and is given by a multivariate normal distribution with unknown mean and variance. LÄS MER
2. Quality Issues in Interview Surveys : Some Contributions
Sammanfattning : In Paper I, I give a brief overview of the “state of the art” in methodological research related to interview surveys and I discuss some implications for survey practices. I study the literature on participation strategies, interviewer effects that can occur during the interview, methods for quality assurance and interviewer training. LÄS MER

4. Two Topics in Survey Methodology : Inference from Nonprobability Samples Using the Double Samples Setup
Sammanfattning : Modelling the response process in establishment surveys proceeded thus far by adding steps of operational character to the core cognitive steps of the individual cognitive model. Here (Paper 1) a larger unit of the cognitive analysis is posited: that part of the enterprise that is engaged in responding to a survey, consisting of one or more employees, the tools they use and the established practices of record keeping and survey responding.

5. On Methods for Real Time Sampling and Distributions in Sampling
Sammanfattning : This thesis is composed of six papers, all dealing with the issue of sampling from a finite population. We consider two different topics: real time sampling and distributions in sampling. The main focus is on Papers A–C, where a somewhat special sampling situation referred to as real time sampling is studied. LÄS MER
