www.stat.berkeley.eduA more revealing expression for the variance of mr is derived in the following: Let ˆj(X,Y)=argmaxj≠Y PΘ(h(X,Θ)=j) so. Definition 2.2 The raw margin function is. Thus, mr(X,Y) is the expectation of rmg(Θ,X,Y) with respect to Θ. For any function f the identity [EΘf (Θ)] 2 =E ... is the standard deviation of rmg(Θ,X,Y) holding Θ fixed. ...
