  1. 1. Event Prediction and Bootstrap in Time Series

    Författare :Anders Svensson; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; bootstrap control.; statistical bootstrap; catastrophe; level-crossings; ARMAX process; Optimal alarm system; time series; optimal event predictor; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Sammanfattning : Alarm systems are used in many situations, and should be as efficient as possible. In this thesis optimal predictive alarm systems, event predictors, are presented for general linear time series models with external signals. This family of process models include e.g. LÄS MER

  4. 3. Variance Expressions and Model Reduction in System Identification

    Författare :Fredrik Tjärnström; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Although system identification is now a mature research field, some problems remain unsolved. Examples of unsolved or partly unsolved problems are; accuracy of subspace identification algorithms, identification via model reduction, identification for control, and identification of non-linear systems.

  5. 4. Quality Estimation of Approximate Models

    Författare :Fredrik Tjärnström; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis discusses three different topics: model error modeling, bootstrap, and model reduction. These subjects may at first sight seem to be quite far away from each other. However, there are some connections between them, the most importantone being uncertainty estimation.Model error modeling is actually a tool for model validation. LÄS MER

  7. 5. Contributions to Small Area Estimation : Using Random Effects Growth Curve Model

    Författare :Innocent Ngaruye; Martin Singull; Dietrich von Rosen; Tapio Nummi; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This dissertation considers Small Area Estimation with a main focus on estimation and prediction for repeated measures data. The demand of small area statistics is for both cross-sectional and repeated measures data. LÄS MER
