  2. 1. Essays on Mergers and Acquisitions and Event Studies

    University dissertation from Stockholm : Stockholm Business School, Stockholm University

    Author : Mohammad Irani; Lars Nordén; Rickard Sandberg; Neslihan Ozkan; [2016]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mergers and acquisitions; event study; prediction; payment method; conditional CAPM; time-varying parameters; structural change methodology; variance; covariance; Business Administration; företagsekonomi;

    Abstract : This dissertation consists of three studies on the anticipation of mergers and acquisitions (M&As) and its impact on takeover event studies. Article I investigates whether the market can anticipate both takeovers and their payment forms prior to their announcement dates. READ MORE

  4. 2. Some properties of measures of disagreement and disorder in paired ordinal data

    University dissertation from Stockholm : Stockholm Business School, Stockholm University

    Author : Hans Högberg; Elisabeth Svensson; Sture Holm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; agreement; augmented ranks; categorical data; disorder; jackknife; paired ordinal data; rating scales; sample size; sampling distribution; simulation; U-statistics; variance; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik; Statistics; Statistik;

    Abstract : The measures studied in this thesis were a measure of disorder, D, and a measure of the individual part of the disagreement, the measure of relative rank variance, RV, proposed by Svensson in 1993. The measure of disorder is a useful measure of order consistency in paired assessments of scales with a different number of possible values. READ MORE

  5. 3. Road profile statistics relevant for vehicle fatigue

    University dissertation from Mathematical Statistics, Centre for Mathematical Sciences, Lund University

    Author : Klas Bogsjö; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; Matematik; Mathematics; model evaluation; vehicle fatigue; stochastic processes; road roughness; Road profiles; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : Road profiles are studied from a vehicle fatigue point of view. A wide range of roads have been measured: from smooth motorways to very rough gravel roads. It is observed that the road profiles consist of irregular sections, which makes the stationary Gaussian model unsuitable (Paper A). READ MORE

  6. 4. Bayesian networks: exact inference and applications in forensic statistics

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Ivar Simonsson; Göteborgs universitet.; Gothenburg University.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian networks; variable elimination algorithm; forensic statistics; relationship inference; mutation models; relationship inference; variable elimination algorithm; forensic statistics; mutation models;

    Abstract : Exact inference on Bayesian networks has been developed through sophisticated algorithms. One of which, the variable elimination algorithm, identifies smaller components of the network, called factors, on which local operations are performed. In principle this algorithm can be used on any Bayesian network. READ MORE
