    Climate change and its subsequent effects on temperature have raised global public health concerns. Although numerous epidemiological studies have shown the adverse health effects of temperature, the association remains unclear for children aged below five years old and those in tropical climate regions.

    Environmental variable importance for under-five mortality in Malaysia: A random forest approach
    (Elsevier, 2022) Vera Ling Hui Phung; Kazutaka Oka; Yasuaki Hijioka; Kayo Ueda; Mazrura Sahani; Wan Rozita Wan Mahiyuddin
    Environmental factors have been associated with adverse health effects in epidemiological studies. The main exposure variable is usually determined via prior knowledge or statistical methods. It may be challenging when evidence is scarce to support prior knowledge, or to address collinearity issues using statistical methods. This study aimed to investigate the importance level of environmental variables for the under-five mortality in Malaysia via random forest approach.
