  1. 1. Local Polynomial Regression with Application on Lidar Measurements

    Författare :Torgny Lindström; Lund University.; Lunds universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik; differential equations; Funktioner; differentialekvationer; variance-function estimation.; spatial dependence; nonparametric; local polynomial regression; local bandwidth selection; lidar; heteroscedasticity; Bivariate estimation; differential absorption; Functions;

    Sammanfattning : This thesis deals with the problem of estimating a function or one of its derivatives from a set of measurements, mainly of a bivariate or spatial nature which is so common in environmental applications. In this work particular attention has been on the lidar (light detection and ranging) application which is a versatile technique for measurement of among other things atmospheric trace gases.

  2. 2. Estimation and optimal designs for multi-response Emax models

    Detta är en avhandling från Stockholm : Department of Statistics, Stockholm University

    Författare :Bergrún Tinna Magnúsdóttir; Stockholms universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multi-response Emax models; Clinical Utility Index CUI ; optimal designs; system estimation; dose-response studies.; statistik; Statistics;

    Sammanfattning : This thesis concerns optimal designs and estimation approaches for a class of nonlinear dose response models, namely multi-response Emax models. These models describe the relationship between the dose of a drug and two or more efficacy and/or safety variables. LÄS MER

  5. 5. Count data modelling and tourism demand

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Jörgen Hellström; Umeå universitet.; [2002]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Time series; Count data; INARMA; Unit root; Aggregation; Forecasting; Tourism; Truncation; Inflation; Simulated maximum likelihood; Bivariate hurdle model.;

    Sammanfattning : This thesis consists of four papers concerning modelling of count data and tourism demand. For three of the papers the focus is on the integer-valued autoregressive moving average model class (INARMA), and especially on the ENAR(l) model. LÄS MER
