W. (2022). Environmental variable importance for under-five mortality in Malaysia: A random forest approach. Science of the Total Environment, 845, 157312.https://repoemc.ukm.my/handle/123456789/1260Environmental 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.enConditional permutation importanceFeature selectionEnvironmental factorMortalityChildrenUnder-fiveJournal
