  1. 21. Integrative genomic and survival analysis of breast tumors

    Författare :Szilard Nemes; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biostatistics; cancer; survival analysis; gemonics; DNA copy number aberrations; messenger RNA;

    Sammanfattning : With the continued accumulation of genomic data at ever increasing resolution the challenge ahead lies in reading out meaningful clinical/biological information form the data that can contribute to a better understanding of the cancerous process. The need for novel approaches, new statistical methods is therefore strong. LÄS MER

    Sammanfattning : In building computer based clinical decision support extensive data analysis is sought to acquire all the medical knowledge needed to formulate the decision rules.This study explores, compares and discusses several approaches to knowledge extraction from medical data. LÄS MER

  4. 23. Novel statistical methods for genome-wide association summary statistics

    Författare :Zheng Ning; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A general objective of genetic studies is to understand the genetic basis of complex traits such as height, body mass index (BMI), disease endpoints, etc. Such researches have been facilitated due to the completion of the human genome project and developments of high-throughput technologies.

  5. 24. Rock Mass Characterisation Using Drill Performance Monitoring : Problems, Analysis challenges and Limitations

    Författare :Rajib Ghosh; Piyush Rai; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Sammanfattning : In open pit mining, it is important to know as much information as possible about rock masses to be mined for more cost-effective mining operation. In rock engineering perspective, information about rock mass characteristics usually includes hardness of the rock, geological features, fractures, faults, ore contacts, water bearing stratum.

  7. 25. Estimation of hazard ratios from observational data with applications related to stroke

    Författare :Guilherme Barros; Jenny Häggström; Marie Eriksson; Daniel Nevo; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; survival analysis; causal inference; hazard ratios; marginal hazard ratio; stroke; balancing; Statistics; statistik;

    Sammanfattning : The objective of this thesis is to examine some challenges that may emerge when conducting time-to-event studies based on observational data. Time-to-event (also called survival) is a setting that involves analyzing how different factors may influence the length of time until an individual experiences the event of interest. LÄS MER
