1. Mimic: A Microscopic Simulation Model for Rural Road Traffic
Sammanfattning : The purpose of this dissertation is to outline the theoretical basis of a road traffic simulation model, named Mimic, that constitutes the key elements of a system for estimating road user effects and environmental impacts. The simulation model suggested is a microscopic road traffic simulation model and it is structured to be used for networks of rural roads. LÄS MER
2. Equity in welfare evaluations : the rationale for and effects of distributional weighting
Sammanfattning : This thesis addresses the issue of weighted cost-benefit analysis (WCBA). WCBA is a welfare evaluation model where income distribution effects are valued by distributional weighting. The method was developed already in the 1970s. The interest in and applications of this method have increased in the past decade, e. LÄS MER
3. Generalised linear models with clustered data
Sammanfattning : In situations where a large data set is partitioned into many relativelysmall clusters, and where the members within a cluster have some common unmeasured characteristics, the number of parameters requiring estimation tends to increase with sample size if a fixed effects model is applied. This fact causes the assumptions underlying asymptotic results to be violated. LÄS MER
4. Latent variable models for longitudinal twin data
Sammanfattning : Longitudinal twin data provide important information for exploring sources of variation in human traits. In statistical models for twin data, unobserved genetic and environmental factors influencing the trait are represented by latent variables. In this way, trait variation can be decomposed into genetic and environmental components. LÄS MER
5. Injuries among children and young adults in Uganda : epidemiology and prevention
Sammanfattning : Injuries are a major morbidity and mortality cause among children and young adults worldwide. Previous Ugandan studies were limited in scope and biased towards severe adulthood injuries in referral care. LÄS MER
