1. Risk-Averse Multi-Armed Bandit Problem with Multiple Plays
University essay from Göteborgs universitet/Institutionen för data- och informationsteknikAbstract : This study aims to construct an efficient heuristic, referred to as RA, for a riskaverse Markovian multi-armed bandit problem (MAB) with multiple plays. The RA incorporates risk-aversion and multiple plays by modifying the Gittins index strategy. READ MORE

2. Branching Out with Mixtures: Phylogenetic Inference That’s Not Afraid of a Little Uncertainty
University essay from KTH/Matematisk statistikAbstract : Phylogeny, the study of evolutionary relationships among species and other taxa, plays a crucial role in understanding the history of life. Bayesian analysis using Markov chain Monte Carlo (MCMC) is a widely used approach for inferring phylogenetic trees, but it suffers from slow convergence in higher dimensions and is slow to converge.

3. Paying the Piper : The Consequences of Including Generic Prices in Reimbursement Decisions for Prescription Pharmaceuticals
University essay from Linköpings universitet/Nationalekonomi; Linköpings universitet/Filosofiska fakultetenAbstract : Objectives: The Dental and Pharmaceutical Benefits Agency (TLV) is responsible for deciding which prescription pharmaceuticals should be subsidized in Sweden. Cost-effectiveness analyses are fundamental to its decision-making, but future price reductions following patent expiry are excluded from these analyses. READ MORE

4. On Predicting Price Volatility from Limit Order Books
University essay from Uppsala universitet/Matematiska institutionenAbstract : Accurate forecasting of stock price movements is crucial for optimizing trade execution and mitigating risk in automated trading environments, especially when leveraging Limit Order Book (LOB) data. However, developing predictive models from LOB data presents substantial challenges due to its inherent complexities and high-frequency nature. READ MORE

5. Optimal Order Placement Using Markov Models of Limit Order Books
University essay from KTH/Matematik (Avd.)Abstract : We study optimal order placement in a limit order book. By modelling the limit order book dynamics as a Markov chain, we can frame the purchase of a single share as a Markov Decision Process. Within the framework of the model, we can estimate optimal decision policies numerically. The trade rate is varied using a running cost control variable. READ MORE
