World Health Organization (WHO) gives the definition of life expectancy at birth as ―the average number of years that a newborn is expected to live if current mortality rates continue to apply‖. Life expectancy at birth is an important indicator of a country's overall health status and its economic and social level of development. In order for governments to set their policies correctly, it is important to determine factors that affect life expectancy at birth and how they affect it. In this thesis, longitudinal data analyses are used to find out the factors that are related with the life expectancy at birth. Specifically, random effects model, marginal model and transition model are used for these analyses. The results suggest that the most suitable model for the data set that is used is marginal model. According to the constructed marginal model, Life Expectancy at Birth is negatively related with Crude Birth Rate (Per Thousand), Crude Marriage Rate (Per Thousand), Crude Death Rate (Per Thousand) and Infant Mortality Rate (Per Thousand). In addition, when measurement error models are fitted under different assumptions of measurement error levels for these four variables, it is seen that only the significance of Infant Mortality Rate changes.

Statistical And Machine Learning Modelling Of Suicıde Rate With Respect To Provinces In Turkey Erdoğan, Süleyman; İlk Dağ, Özlem; Department of Statistics (2022-8-18) There are many factors that can affect the individual’s mental health and thus lead them to commit suicide. This study, focuses on the social and economic factors that may contribute to the suicide rates in all provinces of Turkey. Possible effects of these factors are studied in an 8 year period between 2012-2019 using standard longitudinal data modelling methods and hybrid modelling methods. Standard longitudinal data models include; fixed effect models, random effect models and transition models whereas ...
Determining the role of mutation load in mammalian senescence Somel, Mehmet; Özer, Füsun; Turan, Zeliha Gözde; Koptekin, Dilek; Ghalichi, Ayshin(2016-12-31) In most multicellular species, aging is accompanied by an increasing risk of disease and mortality, a process termed senescence. The evolutionary causes and genetic bases of senescence are little understood. Senescence is usually associated with accumulating cellular damage, although a number of theories suggest that harmful mutations that are expressed only at late age could also contribute to the aging phenotype. Analyzing primate brain transcriptome data, we recently identified a pattern that would suppo...
Reconstruction of Cell Type-Specific Genome-Scale Metabolic Models using Single-cell RNA-Seq Data to Investigate Tumor Metabolism Abdik, Ecehan; Çakır, Tunahan; Pir, Pınar (Orta Doğu Teknik Üniversitesi Enformatik Enstitüsü; 2022-10) Cancer is a global health problem with high mortality and increasing prevalence. Mathematical modeling strategies have a great impact on the pharmaceutical industry through their cost and time-saving effects in drug discovery and development processes. Genome-scale metabolic models (GEMs) have been used to investigate complex disease mechanisms by integrating them with omics data [1]. Cancer has complex and dynamic biology including interactions between tumor cells and microenvironments. Each cell type has ...
Design and development of medical recommendation system for home care service for geriatrics Beşik, Saliha İrem; Alpaslan, Ferda Nur; Department of Computer Engineering (2015) Demands and expectations for health care have gradually increased with the longer life expectancy and decline in birth rate, however the resources reserved for health services are relatively limited. The countries with aging population problems are trying to develop new systems to obtain more effective usage of current resources. The aging population and resultant chronic illnesses has become a real problem for Turkey as well. The increase in elderly population results in more demand for health care because...
Modelling and forecasting age-segmented mortality: evaluation of lLe-Carter method and its extensions Alşan Kılıç, Raife Sıda; Sürücü, Barış; Department of Statistics (2019) Mortality dynamics deal with the human mortality from birth to death giving insights for the population in different aspects; age, year, gender and enable to ascertain crucial mortality trends as well. Over the last decades, ample new methods have been developed and the mortality modelling has been evolved into more effective ways. Among these models, the pioneering and the most seminal one is Lee-Carter model (Lee & Carter, 1992). From its development, Lee-Carter model has been intensively studied and its ...
