Webit subtracts the average of future available observations. The main advantage is that it preserves sample size in panels with gaps. Under differencing, if some x_it is missing, then both D.x_it and D.x_i,t+1 are missing. But under orthogonal deviations, the transformed x_i,t+1 need not go missing. darty ssd 1to
