  3. 2. Self-Normalized Sums and Directional Conclusions

    Författare :Fredrik Jonsson; Allan Gut; Josef Steinebach; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Self-normalized sums; heavy-tailedness; Student s t-statistic; distributional symmetry; exponential tilting; directional conclusions; reversal rates; multiple statistical inference; the Benjamini-Hochberg procedure;

    Sammanfattning : This thesis consists of a summary and five papers, dealing with self-normalized sums of independent, identically distributed random variables, and three-decision procedures for directional conclusions. In Paper I, we investigate a general set-up for Student's t-statistic. LÄS MER

  4. 3. Empirical Bayes Methods for DNA Microarray Data

    Författare :Ingrid Lönnstedt; Allan Gut; Tom Britton; Mette Langaas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; two-channel microarrays; differential expression; replication; empirical Bayes; factorial design; interaction; time trends; hierarchical Bayes; MCMC simulations; ANOVA; F-statistics; Matematisk statistik; Mathematical statistics; Matematisk statistik;

    Sammanfattning : cDNA microarrays is one of the first high-throughput gene expression technologies that has emerged within molecular biology for the purpose of functional genomics. cDNA microarrays compare the gene expression levels between cell samples, for thousands of genes simultaneously.
