1. The Role of Uni- and Multivariate Bias Adjustment Methods for Future Hydrological Projections and Subsequent Decision-Making
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Climate models are essential for generating future climate projections. However, due to simplifications, the models can produce systematic differences between output and reality, which is referred to as model bias. Bias adjustment methods aim to reduce this error, which is important for making future projections more reliable. LÄS MER
2. IPW vs Imputation for Non-response : a simulation study
Master-uppsats, Stockholms universitet/Statistiska institutionenSammanfattning : The non-response is a growing issue and it is effecting the result of survey quality, it can there- fore not be ignored without substantial consequences. There are many methods on how to deal with non-response, both on how to avoid the non-response and how to minimise the con- sequences, like the non-response bias. LÄS MER
3. Evaluation of X-band Weather Radar Data in Urban Hydrology
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : Throughout history it has always been crucial to accurately measure, track, and predict precipitation. This has been done using various methods with varying degrees of precision. As the world evolves and as urban areas expand, it has become more apparent that there is a need for a more efficient way to observe and record precipitation. LÄS MER
4. Outcome regression methods in causal inference : The difference LASSO and selection of effect modifiers
Magister-uppsats, Umeå universitet/StatistikSammanfattning : In causal inference, a central aim of covariate selection is to provide a subset of covariates, that is sufficient for confounding adjustment. One approach for this is to construct a subset of covariates associated with the outcome. This is sometimes referred to as the outcome approach, which is the subject for this thesis. LÄS MER
5. Creation & Assessment of a Video Quality Ruler
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Image quality has always been a matter of great importance for anyone working with or consuming images and videos. Images and videos are, in general, for human consumption. Thus, image quality is essentially a subjective attribute of an image. LÄS MER
