: Let { X k : k ≧ 1 } be a sequence of i.i.d.rv with E ( X i ) = 0 and E ( X 2 i ) = σ 2 , 0 < σ 2 < ∞ . Set S n = X 1 + · · · + X n . Let Y n ( t ) be S k /σn 1 2 for t = k/n and suitably interpolated elsewhere. This paper gives a generalization of a theorem of Iglehart which states weak convergence of Y n ( t ) , conditioned to stay positive, to a suitable limiting process.
