1. Calibration Adjustment for Nonresponse in Sample Surveys
Sammanfattning : In this thesis, we discuss calibration estimation in the presence of nonresponse with a focus on the linear calibration estimator and the propensity calibration estimator, along with the use of different levels of auxiliary information, that is, sample and population levels. This is a fourpapers- based thesis, two of which discuss estimation in two steps. LÄS MER
2. Spatial sampling and prediction
Sammanfattning : This thesis discusses two aspects of spatial statistics: sampling and prediction. In spatial statistics, we observe some phenomena in space. Space is typically of two or three dimensions, but can be of higher dimension. LÄS MER
3. A covariance structure analysis approach to the errors-in-variables estimation problem
Sammanfattning : It is a well-known fact that standard regression techniques, when applied to errors-in-variables (EIV) models, lead to biased and inconsistent parameter estimation. The work presented in this thesis address the EIV estimation problem using covariance structure analysis (CSA). LÄS MER
4. Rood of groen? De interne woordvolgorde in tweeledige werkwoordelijke eindgroepen met een voltooid deelwoord en een hulpwerkwoord in bijzinnen
Sammanfattning : The internal word order in bipartite verb clusters including a past participle in Dutch subordi-nate clauses shows considerable variation. Dutch allows the so-called red word order (auxil-iary - past participle) as in: ‘Ik geloof niet dat hij het heeft gedaan’ as well as the so-called green word order (past participle - auxiliary) as in: ‘Ik geloof niet dat hij het gedaan heeft’.

5. Multiple Kernel Imputation : A Locally Balanced Real Donor Method
Sammanfattning : We present an algorithm for imputation of incomplete datasets based on Bayesian exchangeability through Pólya sampling. Each (donee) unit with a missing value is imputed multiple times by observed (real) values on units from a donor pool. The donor pools are constructed using auxiliary variables. LÄS MER
