Fit exponential distribution in r
WebDetails. The inverse exponential distribution with parameter scale = \theta has density: . f(x) = \frac{\theta e^{-\theta/x}}{x^2} for x > 0 and \theta > 0.. The kth raw moment of the random variable X is E[X^k], k < 1, and the kth limited moment at some limit d is E[\min(X, d)^k], all k..

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 …
