The book also explores the regional complexities involved in the discussion of these topics. It presents a number of specific techniques, such as two-level logistic regression, analysis of mental health, probabilistic and predictive analysis of nutritional deficit, and generalized linear mixed models, that can be used to analyze mortality and morbidity and factors affecting out-of-pocket expenses in the healthcare context.Lastly, it presents concrete case studies substantiating the theoretical models discussed. As such, the book offers a valuable resource for health researchers, professionals and policymakers alike.
