Globally distributed product development : role of complexity in the what, where and how
… In the first study, I use multinomial logistics models and find that product complexity, specificity, strategic importance and designing firm's capability are directly related to the modes of global product development. These modes are namely global partnerships, captive offshoring and global …

Incidence rates of psychostimulant and non-stimulant medications among children and adolescents in Iceland : before, during, and after the COVID-19 pandemic
… at risk, stratified by sex and age group. Negative binomial models were used to model incidence rate ratios (IRR). Results: During 2016–2024, males had significantly higher incidence rates than females, adjusted for year and age group. Compared to the youngest age group (6–8 years) all …

Moose and deer resource selection and co-occurrence in northeast Minnesota
… moose, deer, and P. tenuis, and the resulting negative impact on moose health, is thought to be driven by deer densities. Despite its importance for moose and deer management, only one peer-reviewed study to date has tested the relationship between deer and moose densities, and therefore the …

A Daily Diary Investigation of the Impact of Flexible Work Arrangements on Physical Activity Among University Staff
… diary days. Data were analyzed with multilevel negative binomial models. Daily barriers and use of flextime were associated with lower physical activity. Self-efficacy, telework, work stress, and work-to-family conflict were not significantly associated with daily physical activity. Flexible …

Assessing the Influence of Landscape Characteristics on Bat Fatalities at South Texas Wind Energy Facilities
… and degree of slope. Using generalized linear models, zero-inflated and negative binomial models, and AIC model selection, results indicate that landscape characteristics at the broadest scale (5 km and 25 km) examined were most strongly associated with estimated bat fatality rates. I suggest …

Clinical Implications of HIV-1, HSV-2 Co-infection and Opportunities for Intervention
… follow-up using mixed linear regression models. No significant difference in the rate of CD4 count change was observed in HSV-2 seropositives at +13.6 cells/mm3/year (p=0.12) in univariate analysis, and -4.5 cells/mm3/year (p=0.68) in analysis adjusted for sex, HSV-1, oral and genital HSV …

UNINTENDED EFFECTS OF CHARTER SCHOOL PROGRAMS
… New York between 2000 and 2010, I estimate models comparing changes in housing price differences between school districts and neighborhoods. I find that charter schools do not influence the gap in housing prices between districts but affect the differences in housing values between high and …

Multivariate Analysis of Accident Related Outcomes with Respect to Contemporaneous Correlation and Endogeneity: Application of Simultaneous Estimation Techniques
… analysis tools, specifically crash prediction models, for the purpose of reducing crashes and enhancing highway safety.Crash prediction models based on statistical or econometric modeling techniques are used for a variety of purposes; most commonly to estimate the expected crash frequencies …

Cognitive impairment and service use: The relationship between research and policy
… had on use over the 12 years of study. Using negative binomial models this analysis found that individuals with MCD visited their general practitioner significantly more than individuals who were cognitively healthy. This use almost doubled when individuals had a comorbid condition of …

Identification of Randomized Trials for Inclusion in Meta-Analyses of Treatments for Childhood Acute Lymphoblastic Leukaemia, and Investigation of Factors Leading to Publication Bias
… correlation structures for repeated measures models. Generalised estimating equation (GEE) analysis is used to select an appropriate correlation structure, and a linear mixed effects model serves to confirm this. The conclusions are then discussed in the context of other studies identified. …

Evaluating the application of planning legislation : the Resource Management Act 1991 and forestry investment
… However, econometric analysis using a negative binomial estimator, found that the RMA rules were insignificant and the major factors affecting forestry investment were population density, number and size of farm and experience in forestry.

Assessing Crash Occurrence On Urban Freeways Using Static And Dynamic Factors By Applying A System Of Interrelated Equations
… aims mainly at developing different statistical models related to the road safety. The thesis includes three main sections: 1) overall crash frequency analysis using negative binomial models, 2) seemingly unrelated negative binomial (SUNB) models for different categories of crashes divided based …

Excess mortality in the Glasgow conurbation: exploring the existence of a Glasgow effect
… decile of postcode sector or ward of residence. Negative binomial models of death counts in small areas using local population as the exposure variable were also created; such models allow the calculation of SMRs with adjustment for continuous variables. Covariates used in these models included …

An Economic Analysis of Evolving Health Hazards
… analysis was performed using a random effects negative binomial model to analyze the economic (income and home foreclosures) and biological (mosquitoes) factors associated with human WNV. Tests reveal the presence of spatial autocorrelation in the dependent variable (human WNV). The presence of …
