11. P-SGLD : Stochastic Gradient Langevin Dynamics with control variates
University essay from Linköpings universitet/Statistik och maskininlärningAbstract : Year after years, the amount of data that we continuously generate is increasing. When this situation started the main challenge was to find a way to store the huge quantity of information. READ MORE

12. Prediction of Linear Models: Application of Jackknife Model Averaging
University essay from Uppsala universitet/Statistiska institutionenAbstract : When using linear models, a common practice is to find the single best model fit used in predictions. This on the other hand can cause potential problems such as misspecification and sometimes even wrong models due to spurious regression. READ MORE

13. Evaluating model selection criteria for nuisance models in causal inference : (when the true models are finite mixtures)
University essay from Umeå universitet/StatistikAbstract : When using inverse probability weighting (IPW) and doubly robust (DR) estimators for estimating the causal effect we need to use nuisance models for estimating the propensity scores, and for the DR estimator also the outcome regression. These nuisance models are often created using a selection of covariates, higher order and interaction terms, which require some model selection criteria. READ MORE

14. A Matlab Toolbox for fMRI Data Analysis: Detection, Estimation and Brain Connectivity
University essay from DatorseendeAbstract : Functional Magnetic Resonance Imaging (fMRI) is one of the best techniques for neuroimaging and has revolutionized the way to understand the brain functions. It measures the changes in the blood oxygen level-dependent (BOLD) signal which is related to the neuronal activity. READ MORE

15. Evaluation of a statistical method to use prior information in the estimation of combustion parameters
University essay from Institutionen för systemteknikAbstract : Ion current sensing, where information about the combustion process in an SI-engine is gained by applying a voltage over the spark gap, is currently used to detect and avoid knock and misfire. Several researchers have pointed out that information on peak pressure location and air/fuel ratio can be gained from the ion current and have suggested several ways to estimate these parameters.
