  1. 16. An Empirical Comparison of Static Count Panel Data Models: the Case of Vehicle Fires in Stockholm County

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Svante Pihl; Leonardo Olivetti; [2020]
    Keywords : Low-Mean Count Data; Poisson Regression; Negative-Binomial Regression; Panel Data Models; Vehicle Fires; Distributional Assumptions;

    Abstract : In this paper we study the occurrences of outdoor vehicle fires recorded by the Swedish Civil Contingencies Agency (MSB) for the period 1998-2019, and build static panel data models to predict future occurrences of fire in Stockholm County. Through comparing the performance of different models, we look at the effect of different distributional assumptions for the dependent variable on predictive performance. READ MORE

  5. 19. From the bulge region to the outer disk: Tracing the α-enhancement level in the Galactic thin and thick disks

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Elin Sandvik; [2020]
    Keywords : Chemical abundance; star formation rate; initial-mass function; APOGEE; Milky Way; Physics and Astronomy;

    Abstract : One of the biggest mysteries astronomers wish to unveil is the formation and evolution of galaxies. Properties of our own galaxy, the Milky Way, can provide great insight into these. The star formation rate (SFR) and whether it varies with distance from the galactic centre (GC), is one of these properties. READ MORE

  6. 20. Land cover changes in Southern Sweden from the mid-Holocene to present day: insights for ecosystem service assessments

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Robert O'Dwyer; [2019]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Götaland; Landscape Reconstruction Algorithm; Fossil Pollen; Ecosystem Services; Earth and Environmental Sciences;

    Abstract : Climate change and human impact play a huge role in the sustainability and development of ecosystems and the services they offer to societies over temporal and spatial scales. Fossil pollen-based estimates provide unique information on past land cover change, but to date there are not many methods able to create spatially continuous maps and have a fine scale of land cover changes inferred from pollen information.
