  1. 1. Some Contributions to Description and Validation of the Extreme Value Distribution

    Författare :MirNabi PirouziFard; Statistiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; weighted least squares estimator.; probability plot; power of tests; extreme value distribution; variances and covariances; goodness-of-fit tests; order statistics; Approximations of means;

    Sammanfattning : This thesis focuses on the validation and description of the Gumbel distribution. Since this is a scale and location parameter distribution, the generalized least squares regression of the order statistics on the expected values can be used, without the necessity of iteration, to obtain the best linear unbiased estimates of the parameters.

  4. 3. Identifying Influential Observations in Nonlinear Regression : a focus on parameter estimates and the score test

    Författare :Karin Stål; Tatjana von Rosen; Sune Karlsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Added parameter plot; differentiation approach; influential observation; nonlinear regression; score test; Statistics; statistik;

    Sammanfattning : This thesis contributes to influence analysis in nonlinear regression and in particular the detection of influential observations. The focus is on a regression model with a known mean function, which is nonlinear in its parameters and where the function is chosen according to the knowledge about the process generating the data.

  5. 4. Statistical methods for molecular tissue-profiling

    Författare :Tobias Wängberg; Tyrcha Joanna; Trung Nghia Vu; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Through the advent of sequencing technologies, researchers have been able to map the entire human genome. The next major step is to classify the cells in order to obtain a cellular basis for health and disease. The previous ground for a taxonomy of the human cells have been mainly based on biological function and morphology. LÄS MER

  7. 5. Low-level analysis of microarray data

    Författare :Henrik Bengtsson; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; programmering; aktuariematematik; Statistik; operationsanalys; Statistics; operations research; programming; actuarial mathematics;

    Sammanfattning : This thesis consists of an extensive introduction followed by seven papers (A-F) on low-level analysis of microarray data. Focus is on calibration and normalization of observed data. The introduction gives a brief background of the microarray technology and its applications in order for anyone not familiar with the field to read the thesis. LÄS MER
