   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Phylogenetics; Divergence Time; Likelihood based methods; Non-informative prior; bootstrap support; Matematisk statistik;

   Sammanfattning : This PhD thesis consists of an introduction and five papers, dealing with statistical methods in phylogenetics.A phylogenetic tree describes the evolutionary relationships among species assuming that they share a common ancestor and that evolution takes place in a tree like manner.

3. 2. Bayesian Inference with Unknown Noise Covariance

   Författare :Lennart Svensson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis studies Bayesian methods in statistical signal processing. A central theme is that the treatment of the unknown noise covariance matrix is of chief concern for all scenarios. As a first application, the detection of land mines using infrared techniques is investigated. LÄS MER

4. 3. Estimation of Discrete Parameters in Linear Systems

   Författare :Fredrik Gustafsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Linear models are the by far most commonly used approach for describing physical signals and systems. As a result, the theory of linear models is quite extensive in areas like control theory and signal processing. However, in many applications a linear model is adequate only if some information of discrete nature is available. LÄS MER
