    Abstract : En signal är en fysisk kvantitet som varierar med någon oberoende variabel, t.ex. tid eller rum, som förmedlar information. En signal vars statistiska egenskaper är konstant i tid kallas stationär, medan signaler vars egenskaper varierar med tiden kallas icke-stationära, vilket är de vanligaste i naturen. READ MORE

  2. 2. Modelling and Inference using Locally Stationary Processes : Biomedical applications

    University dissertation from Lund University, Faculty of Science, Centre for Mathematical Sciences, Mathematical Statistics

    Author : Rachele Anderson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lund University.; [2017-11]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Modelling of Time-Varying Signals; Locally Stationary Processes; Statistical Inference; Time-frequency Estimation; Regression; EEG Signals; HRV Signals;

    Abstract : This thesis considers statistical methods for non-stationary signals, specifically stochastic modelling, inference on the model parameters and optimal spectral estimation. The models are based on Silverman’s definition of Locally Stationary Processes (LSPs). READ MORE
