1. 1. 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

   Sammanfattning : In linkage analysis or, in a wider sense, gene mapping one searches for disease loci along a genome. This is done by observing so called marker genotypes (alleles) and phenotypes (affecteds/unaffecteds) of a pedigree set, i.e. LÄS MER
