I am not sure if I can simply fit a Weibull to the inverse of the observations and say then that parameters are the same for inversed weibull. Simple question is, why the estimations can not be done for this dataset and may be somebody know how is it possible to fit inverse weibull and frechet distributions in R? If the latter, this Q would be off-topic for CV (see our. The "distributions" package vignette provides the Distribution also knonw as the log-Gompertz. 1.405.323
