  2. 1. Hidden patterns that matter : statistical methods for analysis of DNA and RNA data

    Author : Therese Kellgren; Patrik Rydén; Sara Sjöstedt de Luna; Rebecka Jörnsten; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Genome; Next-generation sequence; statistics; microarrays; bacteria; antibiotic resistance; inherited diseases; Co-expression networks; centralization within subgroups;

    Abstract : Understanding how the genetic variations can affect characteristics and function of organisms can help researchers and medical doctors to detect genetic alterations that cause disease and reveal genes that causes antibiotic resistance. The opportunities and progress associated with such data come however with challenges related to statistical analysis. READ MORE

  4. 2. Statistical methods for register based studies with applications to stroke

    Author : Anita Lindmark; Marie Eriksson; Xavier de Luna; Eva-Lotta Glader; Saskia le Cessie; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Registers; quality of care; socioeconomic status; hospital performance; stroke; mediation; sensitivity analysis; truncation; censoring; Statistics; statistik;

    Abstract : This thesis adds to the area of register based research, with a particular focus on health care quality and (in)equality. Contributions are made to the areas of hospital performance benchmarking, mediation analysis, and regression when the outcome variable is limited, with applications related to Riksstroke (the Swedish stroke register).

    Abstract : The standard model of particle physics can excellently describe the vast majorityof data of particle physics experiments. However, in its simplest form, it cannot account for the fact that the neutrinos are massive particles and lepton flavorsmixed, as required by the observation of neutrino oscillations. READ MORE

  7. 5. Predictions Within and Across Aquatic Systems using Statistical Methods and Models

    Author : Peter H. Dimberg; Roger Herbert; Andreas C. Bryhn; Gesa Weyhenmeyer; Mikael Malmaeus; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lake; Water quality; Chlorophyll-a; Total phosphorus; Seasonality; Morphometry; Regression model; Probability; Markov chain; Genetic programming; Temporal-trend; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Abstract : Aquatic ecosystems are an essential source for life and, in many regions, are exploited to a degree which deteriorates their ecological status. Today, more than 50 % of the European lakes suffer from an ecological status which is unsatisfactory. READ MORE
