2. 1. Simulation-based Inference : From Approximate Bayesian Computation and Particle Methods to Neural Density Estimation

   Author : Samuel Wiqvist; Matematisk statistik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian statistics; computational statistics; deep learning; mixed­-effects; sequential Monte Carlo; stochastic dif­ferential equations;

   Abstract : This doctoral thesis in computational statistics utilizes both Monte Carlo methods(approximate Bayesian computation and sequential Monte Carlo) and machine­-learning methods (deep learning and normalizing flows) to develop novel algorithms for infer­ence in implicit Bayesian models. Implicit models are those for which calculating the likelihood function is very challenging (and often impossible), but model simulation is feasible. READ MORE

4. 2. Analytical Approximations for Bayesian Inference

   Author : Tohid Ardeshiri; Fredrik Gustafsson; Johan Wolfgang Koch; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Bayesian inference is a statistical inference technique in which Bayes’ theorem is used to update the probability distribution of a random variable using observations. Except for few simple cases, expression of such probability distributions using compact analytical expressions is infeasible. READ MORE

5. 3. Inferring Evolutionary Processes of Humans

   Author : Sen Li; Mattias Jakobsson; Ludovic Orlando; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Approximate Bayesian Computation; TMRCA; demography; human evolution; Bantu-Expansion; Out-of-Africa;

   Abstract : More and more human genomic data has become available in recent years by the improvement of DNA sequencing technologies. These data provide abundant genetic variation information which is an important resource to help us to understand the evolutionary history of humans. READ MORE

6. 4. Neutral and Adaptive Processes Shaping Genetic Variation in Spruce Species

   Author : Michael Stocks; Martin Lascoux; Renaud Vitalis; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; spruce; population genetics; adaptation; evolution; picea; approximate bayesian computation; cline;

   Abstract : Population genetic analyses can provide information about both neutral and selective evolutionary processes shaping genetic variation. In this thesis, extensive population genetic methods were used to make inferences about genetic drift and selection in spruce species. READ MORE

7. 5. Demography and Polyploidy in Capsella

   Author : Kate St.Onge; Anna Palmé; Martin Lascoux; Ulf Lagercrantz; Richard Abbott; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Approximate Bayesian Computation; Mating system; Brassicaceae; flowering time; genetic diversity; Evolution; Biology; Biologi;

   Abstract : Studies of demography and population structure give insight into important evolutionary processes such as speciation and diversification. In the present work I perform such studies in the genus Capsella, which has three species: C. grandiflora, an outcrossing diploid, C. rubella a selfing diploid, and C. READ MORE
