Cambodia is facing the high rate of children mortality in the first 28 days of lifetime. Kratie and Kampong Chhnang provinces have the highest rate of children death because they are one of the poorest province. Kratie has the forest which is the origin of many tropical diseases such as the malaria and the dengue fever (https://en.wikipedia.org/wiki/Krati%C3%A9_Province#cite_note-part1-20). The sanitary of poor households here are not good to prevent and cure the babies. The poverty is a good explanation for the children deaths but it needs more the statistic interpretation of specific factors. We chose four factors that are the electricity accessibility, the healthcare center's distance, the family size, and the violence. Nevertheless, the data-set of children mortality is unreliable due to the replicated data. Thus, the regression is not precise. Only 22% districts have the right regression result. Only 9% overestimated districts has the acceptable error (less than 0.5 child difference).
