1. Model-Based Optimization of Clinical Trial Designs
Sammanfattning : General attrition rates in drug development pipeline have been recognized as a necessity to shift gears towards new methodologies that allow earlier and correct decisions, and the optimal use of all information accrued throughout the process. The quantitative science of pharmacometrics using pharmacokinetic-pharmacodynamic models was identified as one of the strategies core to this renaissance. LÄS MER
2. 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.

3. Survey estimation for highly skewed data
Sammanfattning : Estimation of the population total of a highly skewed survey variable from a small sample is problematic if straightforward methods are used since (i) when there are no extreme values in the sample, too small estimates will be obtained (ii) if extreme values are sampled, the estimates will become grotesquely large. Traditional methods for outlier treatment will usually compensate for outliers in the sample, thereby avoiding (ii), whereas the small negative bias of (i) will persist. LÄS MER
4. Regular inference for reactive systems
Sammanfattning : Models of reactive systems play a central role in many techniques for verification and analysis of reactive systems. Both a specification of the system and the abstract behavior of the system can be expressed in a formal model. Compliance with the functional parts in the specification can be controlled in different ways. LÄS MER
5. Sample Efficient Bayesian Reinforcement Learning
Sammanfattning : Artificial Intelligence (AI) has been an active field of research for over a century now. The research field of AI may be grouped into various tasks that are expected from an intelligent agent; two major ones being learning & inference and planning . LÄS MER
