1. Multiple Kernel Imputation : A Locally Balanced Real Donor Method
Abstract : 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. READ MORE

2. Statistical inference with deep latent variable models
Abstract : Finding a suitable way to represent information in a dataset is one of the fundamental problems in Artificial Intelligence. With limited labeled information, unsupervised learning algorithms help to discover useful representations. READ MORE

3. Statistical modeling in international large-scale assessments
Abstract : This thesis contributes to the area of research based on large-scale educational assessments, focusing on the application of multilevel models. The role of sampling weights, plausible values (response variable imputed multiple times) and imputation methods are demonstrated by simulations and applications to TIMSS (Trends in International Mathematics and Science Study) and PISA (Programme for International Student Assessment) data.

4. Bayesian Cluster Analysis : Some Extensions to Non-standard Situations
Abstract : 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. READ MORE

5. Female sex hormones and health outcomes in women with specific focus on asthma
Abstract : In humans, gender differences exist across a wide spectrum of diseases. For instance, women are more likely to develop Sjogren’s syndrome, systemic lupus erythematosus, and autoimmune thyroid disease compared to men. READ MORE
