On unbiased estimators for functions of the rate parameter of the exponential distribution
Roberto Vila, Eduardo Yoshio Nakano
In this paper, we explicitly derive unbiased estimators for various functions of the rate parameter of the exponential distribution in the absence of a location parameter, includin…

A novel unit-asymmetric distribution based on correlated Fréchet random variables
Roberto Vila, Felipe Quintino
In this paper, we propose a new distribution with unitary support which can be characterized as a ratio of the type , where follows a bivariate e…
