Abstract:
... The Geba basin is one of the most water-stressed areas of Ethiopia, with only a short rainy period from mid-June to mid-September. Because rainfall in this region has been consistently erratic in the last decades, both in time and space, rain-fed agriculture has become problematic. Hence, in order to supplement rain-fed agriculture by irrigation, a detailed understanding of local and regional surf ...

Abstract:
... Studies of the goodness-of-fit test, which describes how well a model fits a set of observations with an assumed distribution, have long been the subject of statistical research. The selection of an appropriate probability distribution is generally based on goodness-of-fit tests. This test is an effective means of examining how well a sample data set agrees with an assumed probability distribution ...

Subject:
probability; probability distribution; rain; China
Abstract:
... The coincidence of precipitation for an inter-basin water transfer project may determine the feasibility of the project and whether there is enough water to be diverted. The degree of coincidence statistically depends upon the spatial dependence of precipitation and can be measured by the multivariate probability distribution. A copula-based approach, which captures such dependence structure, is p ...
