    Author : Bin Sun; Wei Cheng; Prashant Goswami; Guohua Bai; Slawomir Nowaczyk; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Learning; Time Series; Traffic Engineering;

    Abstract : Intelligent transportation systems (ITS) are becoming more and more effective. Robust and accurate short-term traffic prediction plays a key role in modern ITS and demands continuous improvement. READ MORE

  4. 2. Essays on Time Series Analysis : With Applications to Financial Econometrics

    Author : Daniel Preve; Rolf Larsson; Bent Nielsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; non-Gaussian time series; nonnegative autoregression; robust estimation; strong convergence; realized volatility; volatility forecast; forecast comparison; Diebold-Mariano test; Statistics; Statistik;

    Abstract : This doctoral thesis is comprised of four papers that all relate to the subject of Time Series Analysis.The first paper of the thesis considers point estimation in a nonnegative, hence non-Gaussian, AR(1) model. The parameter estimation is carried out using a type of extreme value estimators (EVEs). READ MORE
