The Ibragimov Hasminskii model postulates observing X1, . . . , Xm independent, identically distributed according to an unknown distribution G and Y1, . . . , Yn independent and identically distributed according to ∫ k(·, y)dG(y) where k is known, for example, Y is obtained from X by convolution with a Gaussian density. We exhibit sieve type estimates of G which are efficient under minimal cond...
