“…We notice that M n (u) is a linear functional of ?n(t,u) = EjLibnilCYi^F-^tJ+b^u), te[0,l], ueR p , viz., M n (y) = J v(F l (0) dï*(t,u) = Φ(?£(·,μ)), o and E n (y) is (equivalent to) a functional of ( §£(·,v), FQ( ·,ν)) (see Theorem 4.3), viz., E a (y) J S^F^^y), y) d*(t) = *(?£(·,y), F£(-,y)), o where for te[0,l], veR P , The essential difficulty in the study of the asymptotic properties of M-and Restimators is the nonlinearity of the estimators, and often it is the case that the uniform asymptotic linear approximation of the estimators (Jurecková, 1971(Jurecková, , 1977 The asymptotic normality of R-estimators was studied by Jurecková (1971) general scores with technical assumptions on the structure of the design matrix D n and by Aubuchon (1982) (a proof can be found in Hettmansperger's (1984)) for a specific score. Applying an analogue of the Convexity Lemma (Pollard, 1991), which was established to derive the limit distribution using a technique analogous to the method by Jurecková (1977), Heiler and Willers (1988) relaxed Jurecková's (1971) assumptions on D n .…”
