Elucidation of adaptive physiological mechanisms in migraine can rationalise important epidemiological, clinical, and pharmacological features and sow the seeds for evolution of an integrative synthesis which process, in turn, might herald the creation of a comprehensive thought framework and research vision for migraine.

This book discusses all major topics on survey sampling and estimation. It covers traditional as well as advanced sampling methods related to the spatial populations. The book presents real-world applications of major sampling methods and illustrates them with the R software. As a large sample size is not cost-efficient, this book introduces a new method by using the domain knowledge of the negative correlation between the variable of interest and the auxiliary variable in order to control the size of a sample. In addition, the book focuses on adaptive cluster sampling, rank-set sampling and...
