Statistical modeling to assess drinking water crisis
- 241 Downloads
We modify the beta distribution by adding a parameter ρ ≥ 0 to capture the urgency level with which nations address drinking water crises. In essence, the urgency parameter relates to region’s environmental or development levels. The modified version is named an urgency biased beta distribution (UBBD). Its statistical properties are considered and illustrated by analysis of the drinking water data in the World Health Organization (2011) report. The methodology of this article is applicable to similar data sets arising in ecological, engineering, medical, business, marketing, and communication, etc. studies.
