Let X1 be a sample of size 1 from the uniform distribution on the interval (−θ,θ) with p.d.f. f(x;θ)=(2θ)−1I{x∈(−θ,θ)} and unknown parameter θ>0 (a*) Show that T:=∣X1∣ is a complete and sufficient statistic. (b*) Show that T and Z:=sign(X1) are independent from each other.
(a) To show that $T=|X_1|$ is a sufficient statistic for $\theta$, we need to show that the conditional distribution of $X_1$ given $T=t$ depends on $\theta$ only through $t$.
