WebJun 22, 2024 · The null hypotheses for these tests are that the distribution is what you think it is. The alternative is that the distribution is NOT what you are testing against. So the tinier p-values mean that a particular distribution is not a good candidate for fit. WebIn this article, we introduce a new three-parameter distribution called the extended inverse-Gompertz (EIGo) distribution. The implementation of three parameters provides a good reconstruction for some applications. The EIGo distribution can be seen as an extension of the inverted exponential, inverse Gompertz, and generalized inverted exponential … can hermit crabs live together
