  1. 1. Prostate cancer incidence, treatment and mortality : Empirical longitudinal register-based studies and methods for handling missing data

    Författare :Marcus Westerberg; Rolf Larsson; Hans Garmo; Pär Stattin; Jimmy Olsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistics; mathematics; prostate cancer; missing data; survival analysis; longitudinal models; incidence; treatment; mortality; Mathematical Statistics; Matematisk statistik; Statistics; Statistik; Urologi; Urology; Epidemiologi; Epidemiology;

    Sammanfattning : The diagnostic activity for prostate cancer has increased substantially in Sweden, primarily due to increased use of prostate-specific antigen (PSA) testing in asymptomatic men, and this has led to a large increase in diagnoses. There have also been changes in the diagnostic workup, guidelines, treatment strategies, and more effective treatments have been introduced in different phases of the disease. LÄS MER

  3. 2. Monotonic regression for large multivariate datasets

    Författare :Oleg Sysoev; Panos Pardalos; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; Statistik;

    Sammanfattning : 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. LÄS MER

  4. 3. Univariate and Multivariate Surveillance of Outbreaks

    Författare :Linus Schiöler; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; change-points; expected delay; exponential family; false alarms; generalised likelihood; inference principles; influenza; MEWMA; monitoring; multivariate; ordered regression; performance metrics; outbreak; predictive value; subjective judgment; spatial; statistical models; surveillance; tularemia;

    Sammanfattning : In many areas there is a need to monitor observations in order to detect changes in the underlying processes as quickly as possible. The theory of statistical surveillance provides the possibility of making optimal decisions about whether a change has occurred or not based on the data available at the time of the decision.

  5. 4. Contributions to multivariate process capability indices

    Författare :Ingrid Tano; Anders Lundquist; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematisk statistik inriktning industriell statistik; Mathematical Statistics with special emphasis on Industrial Statistic; Matematisk statistik; Matemathical Statistics; Manufacturing and materials engineering;

    Sammanfattning : The work presented in this thesis considers multivariate process capability indices (MPCIs) with focus on confidence intervals and tests for MPCIs. It also includes a case study, where multivariate statistical analysis and MPCIs are applied to data from a thermal spraying process at Volvo Aero Corporation. LÄS MER
