1. Evaluation of climate model simulations by means of statistical methods
Sammanfattning : Evaluation of climate model simulations is a key issue within climate research. The statistical framework proposed by Sundberg et al., 2012, provides a theoretical underpinning of methods for evaluation of climate models by use of climateproxy data from the last millennium. LÄS MER
2. Towards a flexible statistical modelling by latent factors for evaluation of simulated responses to climate forcings
Sammanfattning : In this thesis, using the principles of confirmatory factor analysis (CFA) and the cause-effect concept associated with structural equation modelling (SEM), a new flexible statistical framework for evaluation of climate model simulations against observational data is suggested. The design of the framework also makes it possible to investigate the magnitude of the influence of different forcings on the temperature as well as to investigate a general causal latent structure of temperature data.

3. Diet and renal cell carcinoma
Sammanfattning : Renal cell carcinoma (RCC) represents 80-85% of all tumors of the kidney and is responsible for about 2% of all cancer deaths in developed countries. Its incidence varies among countries, among migrants, and by socioeconomic status suggesting that environmental factors play a major etiological role. LÄS MER
