Godambe's Non-existence Theorem - Revisited & Refined Through Matrix Arguments
Abstract: In the context of a finite labeled population, for estimation
of a population total or mean, there does not exist any umvue, unless the
sampling design is trivially a cluster sampling design. This is the celebrated
Godambe's non-existence theorem. Basu established another version of it.
We revisit the proof and strengthen the result by using matrix arguments.
