Fisher information for geometric distribution

WebShow that the family of geometric distributions is a one-parameter exponential family with T(x)=x. [Hint: xα =eαlnx,forx>0.] Solution Recall that the pmf of a one-parameter (θ) exponential family is of the form p(x θ)=h(x)eη(θ)T(x)−B(θ), where x ∈X. Rewriting the pmf of a Geometric random variable yields P θ {X = x} =e(x−1)ln(1− ...
