If anyone know how to do it, would you please >help me? You might try a vector of series. Call it seriesvec; so somewhere you'll have to have: DECLARE VECT[series] seriesvec Suppose it is going to be constist of n series, some at some point you'll have DIMENSION seriesvec(n) Then in your loop you'll do whatever you need to do to generate the series, e.g. creating n series of AR(1)'s, DO ii = 1,n SET(first=0.) SERIESVEC(ii) start end = .75*SERIESVEC(ii){1} + %ran(1.) END DO ii or DO ii = 1,n SET SERIESVEC(ii) start end = 0. SET e start end = %ran(1.) DO jj = start+1,end COMPUTE SERIESVEC(ii)(jj) = .75*SERIESVEC(ii)(jj-1) + e(jj) END DO jj END DO ii I hope this helps. --Norm Norman J.
