Estimating equations for a real parameter which indexes a family of densities p (x, ) were considered in the note by Godambe (Ann. Math. Statist. 31 (1960) 1208-1211). An optimality property of the equation p/ = 0 among unbiased estimating equations was established. In this paper an analogous result is proved for estimation of a real parameter ₁ in the presence of a nuisance parameter ₂.
