  1. 1. On Non Parametric Regression and Panel Unit Root Testing

    Author : Xijia Liu; Rolf Larsson; Johan Lyhagen; Niklas Ahlgren; Uppsala universitet; []

    Abstract : In this thesis, two different issues in econometrics are studied, the estimation of regression coefficients and the non-stationartiy analysis in a panel setting.Regarding the first topic, we study a set of measure of location-based estimators (MLBEs) for the slope parameter in a linear regression model with a single stochastic regressor.

  2. 2. Monotonic regression for large multivariate datasets

    Author : Oleg Sysoev; Panos Pardalos; Linköpings universitet; []

    Abstract : Monotonic regression is a non-parametric statistical method that is designed especially for applications in which the expected value of a response variable increases or decreases in one or more explanatory variables. Such applications can be found in business, physics, biology, medicine, signal processing, and other areas. READ MORE

  3. 3. Weighted Regression with Application to Array Antennas

    Author : Astrid Lundgren; Chalmers University of Technology; []
    Keywords : array antenna; weighted regression; statistical estimation theory; modelling; calibration;

    Abstract : A nonlinear system can be modelled with a simple linear model ifthe model is only valid locally. This can be done by assigningweights to the estimation data, as a function of the distance tothe modelled point. The weighting is here used to develop adirection-dependent calibration method for array antennas. READ MORE

  4. 4. Some Investigations into the Class of Exponential Power Distributions

    Author : Lukas Arnroth; M. Rauf Ahmad; Patrik Andersson; Matúš Maciak; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Exponential power distribution; Skewed exponential power distribution; linear mixed models; score test; Lp-quantiles; quantile regression; posterior convergence rate; Statistics; Statistik;

    Abstract : In this thesis, methods are developed relating to the exponential power class of distributions.Paper I considers Bayesian linear mixed models where the usual normality assumption is replaced by the multivariate exponential power distribution. Particular focus lies on Bayesian testing of the fixed effects. READ MORE

  5. 5. Statistical Methods for Taxon Classification and Bird Migration Phenology

    Author : Måns Karlsson; Ola Hössjer; Jonas Knape; Benjamin Bolker; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Classification; quantile regression; phenology; statistical ornithology; L-functionals; set-valued classification; species identification; statistical ecology; multispecies modelling; matematisk statistik; Mathematical Statistics;

    Abstract : The connection between ecology and statistics is deep. Methodological advancement in statistics open up new possibilities to understand the distribution of life on earth, and research questions in ecology cause new statistical methods to be developed. READ MORE
