I am trying to write the pdf of a beta random variable in its biparametric canonic form such as: Function 1 fY(y;θ,ϕ)=exp{ϕ[yθ−b(θ)]+c(y,ϕ)}1A(y)fY(y;θ,ϕ)=exp{ϕ[yθ−b(θ)]+c(y,ϕ)}1A(y) My work so far: First, I use the beta function ...
we introduce a generalization—referred to as the beta Gumbel distribution—generated from the logit of a beta random variable. We pro- vide a comprehensive treatment of the mathematical properties of this new distribution. We derive the analytical shapes of the corresponding probability density functio...
