  1. 6. Bias approximation and reduction in vector autoregressive models

    Författare :Tomas Brännström; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : In the last few decades, vector autoregressive (VAR) models have gained tremendous popularity as an all-purpose tool in econometrics and other disciplines. Some of their most prominent uses are for forecasting, causality tests, tests of economic theories, hypothesis-seeking, data characterisation, innovation accounting, policy analysis, and cointegration analysis.

  3. 7. Bias and Precision in Biomechanical Exposure Assessment : Making the Most of our Methods

    Författare :Jennie Jackson; Svend Erik Mathiassen; Eva Vingård; Mikael Forsman; Peter Johnson; Högskolan i Gävle; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; measurement strategy; accuracy; inclinometry; electromyography; EMG; upper arm; shoulder; low back; lumbar; thoracic; Health-Promoting Work; Hälsofrämjande arbete;

    Sammanfattning : Background: Insufficient exposure assessment is a suggested contributing factor to the current lack of clearly characterised relationships between occupational biomechanical risk factors and musculoskeletal disorders. Minimal attention has been paid to the potential bias of measurement tools from expected true values (i.e. LÄS MER

  4. 8. Criminal investigation: Motivation, emotion and cognition in the processing of evidence

    Författare :Karl Ask; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Criminal investigation; motivation; emotion; Hindsight bias; police; investigate;

    Sammanfattning : This thesis examines biases in judgments made in the context of criminal investigation, drawing theoretically on frameworks developed in social and cognitive psychology. Study I investigated the existence of confirmation bias in the interpretation of criminal evidence, and the need for cognitive closure (NFC) as a potential moderator. LÄS MER

  5. 9. Essays on Banking and Portfolio Choice

    Författare :Bo Larsson; Hans Wijkander; Jean-Charles Rochet; Stockholms universitet; []
    Nyckelord :Optimal reserves; Time-diversification; Home bias;

    Sammanfattning : This thesis consists of three self-contained essays in the fields of banking and portfolio choice.Banking and Optimal Reserves in an Equilibrium Model:I address the question of reserves in banking, particularly the fact that reserves are substantially larger than the stipulated reserve requirements by Bank of International Settlements.

  7. 10. Seasonal Adjustment and Dynamic Linear Models

    Författare :Can Tongur; Daniel Thorburn; Sune Karlsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dynamic linear models; DLM; direct and indirect seasonal adjustment; relative efficiency; Huber loss function; Polls of polls; Wiener process; Swedish elections; Statistics; statistik;

    Sammanfattning : Dynamic Linear Models are a state space model framework based on the Kalman filter. We use this framework to do seasonal adjustments of empirical and artificial data. A simple model and an extended model based on Gibbs sampling are used and the results are compared with the results of a standard seasonal adjustment method. LÄS MER
