1. 1. Exploring the Impact of Pseudo and Quasi Random Number Generators on Monte Carlo Integration of the Multivariate Normal Distribution

   University essay from Lunds universitet/Statistiska institutionen

   Author : Marcus Stolz; Jonathan Christopher; [2024]
   Keywords : Monte Carlo integration; Quasi monte carlo integration; Random number generation; Mathematics and Statistics;

   Abstract : This thesis examines the effects of pseudo and quasi-random number generators on the accuracy and efficiency of Monte Carlo Integration in the case of the multivariate normal distribution. The study compares the performance of the Mersenne Twister (a pseudo-random number generator) with Sobol and Halton sequences (quasi-random number generators). READ MORE

3. 2. Regularization Methods and High Dimensional Data: A Comparative Study Based on Frequentist and Bayesian Methods

   University essay from Lunds universitet/Statistiska institutionen

   Author : Markus Gerholm; Johan Sörstadius; [2024]
   Keywords : Linear regression; high dimensional data; regularization; Bayesian methods; Mathematics and Statistics;

   Abstract : As the amount of high dimensional data becomes increasingly accessible and common, the need for reliable methods to combat problems such as overfitting and multicollinearity increases. Models need to be able to manage large data sets where predictor variables often outnumber the amount of observations. READ MORE

5. 4. The Sustainable Era - The Excess Return on Swedish Sustainable Global Equity Funds

   University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

   Author : Kristoffer Holmgren; Måns Hurtigh; [2023-07-03]
   Keywords : Fama-French; ESG; Morningstar; Morningstar Globe Rating; funds; global equity funds; sustainability; excess return;

   Abstract : This thesis explores the relationship between the performance of Swedish global equity funds and the level of sustainability, as measured by the Morningstar Globe Rating, using a Fama-French six-factor model, globe rating categories, and time effects. Treating the Morningstar Globe Rating as a time-invariant variable, a sample of 80 Swedish global equity funds are divided into two sustainability groups, ‘Low’ and ‘High’, grouping funds with 1-3 globes into a reference group.

6. 5. Sensitivity of Norway Spruce (Picea abies) to inundation.

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Whitney Cleopatra Vlahakis; [2023]
   Keywords : Inundation; riparian zone; spruce seedlings; restoration; mortality;

   Abstract : Alteration of river flow regimes due to dams result in modifications of riparian ecosystem, with impacts on vegetation, landforms, and habitats. A key characteristic that differentiates riparian zones from adjacent aquatic and terrestrial environments is the event of periodic flooding and water logging. READ MORE
