  2. 7. Pharmacometric Investigations of Prediction Precision and Advances of Models for Composite Scale Data

    Författare :Gustaf Wellhagen; Maria C. Kjellsson; Bengt Hamrén; Per Olsson Gisleskog; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacometrics; modelling; non-linear mixed effects modelling; composite scale data; total score data; total score analysis; precision prediction; bounded integer; bounded integer model; IRT-informed total score analysis; item response theory-informed; mixed models for repeated measures; MMRM; dose-response; dose-response mixed models for repeated measures; DR-MMRM; HbA1c models; fit-for-purpose analysis; clinical trial analysis; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Clinical trials are needed to evaluate new treatments. In late-stage clinical trials, failures are mostly due to lack of efficacy. Fit-for-purpose analysis methods will likely increase the success rates and advance drug development by providing higher precision to support decisions such as go/no-go, dose selection, or sample size.

  3. 8. Economic Analyses of Drinking Water and Sanitation in Developing Countries

    Författare :Therése Hindman; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ekonomisk teori; Nationalekonomi; ekonometri; economic policy; economic systems; economic theory; econometrics; Economics; Discrete Choice; Welfare; Child Health; Water and Sanitation; Household Demand; ekonomiska system; ekonomisk politik; Public health; epidemiology; Folkhälsa; epidemiologi; Environmental health; Miljömedicin;

    Sammanfattning : This thesis focuses on different aspects of household demand, and the determinants of demand, for water and sanitation related inputs fundamental to the households' well-being, i.e. drinking water and toilet facilities. The thesis consists of five chapters, one introductory chapter and four self-contained, essentially empirical, studies. LÄS MER

  4. 9. Learning about the unobservable : The role of attitudes, measurement errors, norms and perceptions in user behaviour

    Författare :Juan Manuel Lorenzo Varela; Yusak Susilo; R. Daniel Jonsson; Maria Börjesson; Soora Rasouli; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attitudes; Measurement errors; Discrete choice analysis; Latent variables; Model misspecification; Normative beliefs; Rail factor; User perceptions; Social norms; Value of travel time savings; Transportvetenskap; Transport Science;

    Sammanfattning : Unobservable factors are important to understand user behaviour. Moreover, they contain information to help design services that willsolve today’s challenges. Yet, we have barely scratched the surface ofthe underlying mechanisms ruling user behaviour. LÄS MER

  5. 10. The Analysis of Duration and Panel Data in Economics

    Författare :Wolfgang Hess; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Monetary Exchange Rate Model; Homogeneity Testing; Panel Cointegration; Pooling; Duration of Trade; Unemployment Duration; Proportional Hazards; Unobserved Heterogeneity; Hazard Rate; Discrete-Time Duration Model; Threshold Excess Model;

    Sammanfattning : This thesis is divided into two distinct parts. The first part contains three chapters dealing with the analysis of duration data from an econometric perspective and with application to trade durations. LÄS MER
