    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Image classification; strong mixing; spatio-temporal model; autocorrelation model; autocorrelation estimator; robustness aspects; strong consistency; asymptotic normality; evaluation; Statistik; Statistics;

    Sammanfattning : The subject of this thesis is methods for classifying land using satellite images, and adherent parameter estimation. A satellite image consists of a set of pixels where measurements of spectral intensities are observed. Based on these spectral intensities, each pixel is assigned a class. LÄS MER

  3. 2. On the Application of Short-term Causal Models

    Författare :Anders Baudin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Causal (econometric) models are often employed as instruments for for-casting in short-term planning within organizations. The aim of this work is to contribute to an understanding of the short-term aspects of causal model building. LÄS MER
