In this paper, the asymptotic normality of twosample linear rank statistics, in case where ties are present, is established. We consider two most important classes of score functions: α,N,(i)=φ(i/(N+1)) and α,N,(i)=Eφ(U,(i),), where U,(1),≤…≤U,(N), are the ordered samples drawn from the population R(0, 1). Several theorems are proved under fairly general conditions concerning the score function φ and the underlying distribution F.
