Thanks to increasing computational resources, the grid sizes of global climate and weather prediction models are decreasing to scales at which subgrid processes, especially the evolution of clouds, can become spatially too variable for traditional deterministic parameterization approaches. We propose a stochastic parameterization in which clouds...

Om goed te kunnen voorspellen waar, wanneer en hoeveel het gaat regenen is het belangrijk om satellietbeelden, weermodellen en grondmetingen te combineren. Het in 2007 opgezette project 'The Trans-African Hydro-Meteorological Obsevatory' (TAHMO) heeft de afgelopen jaren 500 goedkope weerstations geplaatst, verspreid over 21 landen in Sub-Sahara...

When a second tumor arises in the contralateral breast in a patient with a previous or synchronous breast cancer, it is of clinical importance to determine if this tumor is a new unrelated tumor or a metastasis, i.e. clone, of the primary tumor. A new, unrelated tumor may be treated similarly as the first one since treatment was successful,...

As Machine Learning models are being applied to a wide range of fields, the potential impact that these algorithms can have on people's lives is increasing. In a growing number of applications, such as criminal justice, financial assessments, job and college applications, the data points are indeed people's profiles. Therefore, in the presence...

For modelling microstructures of materials the Voronoi diagram is one of the most commonly used models. In this thesis we study a generalization of Voronoi diagrams known as the Laguerre-Voronoi diagram. In particular, we consider the stereological problem of estimating the 3D cell volume distribution of such a diagram from one of its 2D planar...

The goal of this thesis is to implement and experiment with a Bayesian way of estimating a (smooth) monotone regression function by applying it to climate data. The method we use is proposed by Neelon and Dunson. This method uses a piece-wise linear model for the unknown regression function and enforces the monotonicity constraint by the...

Porous asphalt resides on most top layers of Dutch roads. Scheduling maintenance for these roads is generally dependent on several factors, but ravelling, the loss of aggregates in the top layers, is the main reason for maintenance on Dutch roads. With the recent framework of the DOS-LCMS scheme generating values for aggregate loss in...

In the past few decades telescopes have given us insight into the structures of the observable universe. Current and future astronomical research investigate problems that concern how these structures have been formed and at which rates cosmic structures grow. The redshift of galaxies plays a fundamental role in this research directions, since...

The likelihood ratio is a generally accepted measure for the strength of evidence in forensic comparison problems. These problems concern comparisons where it is investigated whether at least two items come from the same source or not, e.g. whether the DNA on the crime scene comes from the suspect or not. The use of likelihood ratios by forensic...

In this report we applied the marginal structural model and the naive Cox model on a simulated dataset, in order to find differences between these models. The marginal structural model is used to estimate causal effects in case of time-dependent confounding via inverse probability weights. The naive Cox model may produce a bias estimate of the...

The estimation of extreme quantile curves of a family of conditional distributions is a non-trivial problem, due to the data-sparseness in the tail of the distribution. This thesis considers the problem of post-processing extreme precipitation forecasts in Friesland from the numerical weather prediction model HARMONIE. Assuming forecasts are...

Coaches can benefit from objective information about playing styles applied in football matches. In this work, two methods for determining (characteristics of) the playing style of a football team in a certain match based on statistics of ball actions are constructed. The first method assigns a match to one of four commonly applied playing...

Let us start with a random sample X1, . . . , Xn that is independent and identically distributed and has distribution function F. When we wish to test the hypothesis H0 : F = F0 for some known function F0, we are doing a goodness of fit test. To do a goodness of fit test, several test statistics can be used. Examples are the Kolmogorov-Smirnov...

Record linkage is the procedure of bringing together information from two or more records that are believed to belong to the same entity. The linking of a pair of records without identifier should be based on attributes both records have in common. The probabilistic framework described by Fellegi and Sunter (1969) can be used for record linkage....

In dit verslag is onderzocht of er geld te verdienen valt aan het spelen van online voetbaltoto. Er zijn twee modellen onderzocht; één op basis van onderlinge resultaten en de ander op basis van achtergrondvariabelen. Vervolgens zijn deze getest op fictieve en historische data en met elkaar vergeleken. Als conclusie is er gevonden dat er zeker...

In this research, a stochastic model for attenuation in Computer Tomography is developed. This model gives rise to the idea of using path dependent variance of the measurements (instead of constant variance) to improve image reconstruction. The distribution of the measurements in this model is determined and a difference with the current...

Jaarlijks worden meer dan 10.000 mannen in Nederland gediagnosticeerd met prostaatkanker en overlijden ruim 2500 mannen aan deze ziekte. Vanwege de omvang van deze (mogelijk) dodelijke ziekte wordt er mede door de European Randomized Study of Screening for Prostate Cancer (ERSPC) al jaren onderzoek gedaan naar de ziekte. De beschikbare dataset...

In statistics one often encounters the problem of estimating a function based on a given dataset. Sometimes shape properties such as monotonicity of the function are known. This property can be used in a non-parametric regression model. The iterative convex minorant(ICM) algorithm can be used to compute an estimate of a convex regression...
