Moreover, they also show probable high risk areas in the future epidemics. These models are based on previous trends of incidents and climate factors. Thus they allow for better prediction of disease incidents or outcomes.
Literature review planning is a crucial step. Not only does it give the researcher a clear map of the entire study, but it also simplifies the process of writing.
A well-structured literature review has many components and is the key to a successful research. The literature review needs a logical and clear structure for a rich understanding.
There are several types of literature review techniques that can be followed in a thesis. They depend on the type of research and the purpose of the study.
