  1. 1. Testing Homogeneity and Unit Root Restrictions in Panels

    Author : Johan Blomquist; [2012]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Non-stationary panels; Panel unit root tests; Cross-sectional dependence; Homogeneity testing;

    Abstract : This thesis is divided into two distinct parts. The first part contains three chapters, co-authored with Joakim Westerlund, that deal with the analysis of unit root testing, and the second part consists of two chapters on slope homogeneity testing. READ MORE

  2. 2. The Analysis of Duration and Panel Data in Economics

    Author : Wolfgang Hess; [2010]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Monetary Exchange Rate Model; Homogeneity Testing; Panel Cointegration; Pooling; Duration of Trade; Unemployment Duration; Proportional Hazards; Unobserved Heterogeneity; Hazard Rate; Discrete-Time Duration Model; Threshold Excess Model;

    Abstract : This thesis is divided into two distinct parts. The first part contains three chapters dealing with the analysis of duration data from an econometric perspective and with application to trade durations. READ MORE

    Abstract : This thesis presents results in Extreme Value Theory with applications to High-Throughput Screening and Bioinformatics. The methods described here, however, are applicable to statistical analysis of huge datasets in general. The main results are covered in four papers. READ MORE

  4. 4. Image-based dynamic liver testing : Studies of segmental hepatic parenchymal function and biliary flow using dynamic 99Tcm-HIDA SPECT

    University dissertation from Stockholm : Karolinska Institutet, Department of Medicine

    Author : Eduard Jonas; Karolinska Institutet.; Karolinska Institutet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dynamic SPECT; Segmental liver function test; Primary sclerosing cholangitis; Bile flow; Bile scintigraphy;

    Abstract : The aim of the study was to create a dynamic liver function test using a tomographic imaging procedure as sampling method. The liver has multiple and complex functions. It is obvious that no single test can give a comprehensive measurement of total liver function. READ MORE

  5. 5. Aspects of multilinear algebra in statistical analysis of seasonal multivariate time series

    University dissertation from Department of Mathematical Statistics, Lund University

    Author : Björn Holmquist; Lunds universitet.; Lund University.; [1985-06-07]

    Abstract : Representations of concepts from multivariate statistics are studied using multilinear algebra. Applications are given to the analysis of seasonal multivariate time series. The first paper concerns a class of permutation matrices which are representations of permutation operators on tensor spaces. READ MORE
