  1. 1. Model Selection

    University dissertation from Uppsala universitet

    Author : Yngve Selén; Uppsala universitet.; Uppsala universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Abstract : Before using a parametric model one has to be sure that it offers a reasonable description of the system to be modeled. If a bad model structure is employed, the obtained model will also be bad, no matter how good is the parameter estimation method. There exist many possible ways of validating candidate models.

  2. 2. Model Selection and Sparse Modeling

    University dissertation from Uppsala : Institutionen för informationsteknologi

    Author : Yngve Selén; Uppsala universitet.; Uppsala universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model selection; model order selection; model averaging; nested models; sparse models; Bayesian inference; MMSE estimation; MAP estimation; ML estimation; AIC; BIC; GIC; RAKE receivers; pulse compression; radar; linear models; linear regression models; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Abstract : Parametric signal models are used in a multitude of signal processing applications. This thesis deals with signals for which there are many candidate models, and it is not a priori known which model is the most appropriate one. READ MORE

  3. 3. Selection and moral hazard in health insurance taking contract theory to the data

    University dissertation from Stockholm : Economic Research Institute, Stockholm School of Economics [Ekonomiska forskningsinstitutet vid Handelshögskolan] (EFI)

    Author : Erik Grönqvist; Handelshögskolan i Stockholm.; [2004]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Asymmetric information; Adverse selection; Moral hazard; Dental care; Difference-in-differences; Propensity score matching; Endogeneity; Selection bias; Advantageous selection; Selection; Informational updating; Empirical test; Contract theory; Health insurance; SOCIAL SCIENCES Business and economics Economics; SAMHÄLLSVETENSKAP Ekonomi Nationalekonomi;

    Abstract : Asymmetric information is a large potential problem for insurance markets, especially for markets insuring health risk. Despite a large theoretical attention over the last 30 years, the empirical evidence of the extent of the problem is still limited. In part this is due to methodological problems. READ MORE

  4. 4. Robust inference of gene regulatory networks System properties, variable selection, subnetworks, and design of experiments

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Torbjörn E. M. Nordling; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; network inference; reverse engineering; variable selection; model selection; feature selection; subset selection; system identification; system theory; network theory; subnetworks; design of experiments; perturbation experiments; gene regulatory networks; biological networks;

    Abstract : In this thesis, inference of biological networks from in vivo data generated by perturbation experiments is considered, i.e. deduction of causal interactions that exist among the observed variables. Knowledge of such regulatory influences is essential in biology. READ MORE

  5. 5. eScience Approaches to Model Selection and Assessment Applications in Bioinformatics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Eklund; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; high-throughout biology; eScience; model selection; model assessment; TECHNOLOGY Bioengineering Bioinformatics; TEKNIKVETENSKAP Bioteknik Bioinformatik;

    Abstract : High-throughput experimental methods, such as DNA and protein microarrays, have become ubiquitous and indispensable tools in biology and biomedicine, and the number of high-throughput technologies is constantly increasing. They provide the power to measure thousands of properties of a biological system in a single experiment and have the potential to revolutionize our understanding of biology and medicine. READ MORE
