This exploratory data analysis finds a negative relationship between some types of war and HIV prevalence (i.e. as the former increases in intensity, the latter decreases). The study uses a longer time-frame and broader range of countries than similar studies, with explicit differentiation between sub-Saharan African and other developing countries. The study uses a variety of methods for analyzing time-series-cross-section data. These methods serve as both a robustness check for the results as well as a real-world demonstration of common suggestions for TSCS data.
