  1. 1. Regression Analysis of Censored Data with Applications in Perimetry

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

    Author : Anna Lindgren; Lunds universitet.; Lund University.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; censored covariate; L_1 minimization; right-censoring; Quantile regression;

    Abstract : This thesis treats regression analysis when either the dependent or the independent variable is censored. We deal with quantile regression when the dependent variable is censored. 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.; 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

  3. 3. Three Phase Controlled Fault Interruption Using High Voltage SF6 Circuit Breakers

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

    Author : Richard Thomas; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; controlled switching; high voltage; hypothesis testing; circuit breakers; fault interruption; least mean squares regression; power system protection;

    Abstract : A method is presented for implementing controlled fault interruption,using high voltage, SF6 circuit breakers on three phase high voltage powernetworks. The main goal of the method is to synchronize the opening or tripcommands to each phase of a circuit breaker with respect to target currentzero times so that each phase will interrupt with a preselected arcingtime.

  4. 4. A two-step regression method with connections to partial least squares and the growth curve model

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

    Author : Ying Li; Sveriges lantbruksuniversitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Prediction of a continuous response variable from background data is considered. The independent prediction variable data may have a collinear structure and comprise group effects. A new two-step regression method inspired by PLS (partial least squares regression) is proposed. READ MORE

  5. 5. Estimation and Inference for Quantile Regression of Longitudinal Data With Applications in Biostatistics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Andreas Karlsson; Uppsala universitet.; [2006]
    Keywords : Statistics; Bias correction; Bootstrap; Dependent errors; Hypothesis testing; Nonlinear model; Simulation study; Statistik;

    Abstract : This thesis consists of four papers dealing with estimation and inference for quantile regression of longitudinal data, with an emphasis on nonlinear models.The first paper extends the idea of quantile regression estimation from the case of cross-sectional data with independent errors to the case of linear or nonlinear longitudinal data with dependent errors, using a weighted estimator.
