Abstract: | Summary We study partial sums of a stationary sequence of dependent random variables of the form

are i.i.d. integer valued, and (n), n![isin](/content/p15332q626768540/xxlarge8712.gif) are also i.i.d. and independent of the X's. It is assumed that the X's and 's belong to the domains of attraction of different stable laws of indices 1<![agr](/content/p15332q626768540/xxlarge945.gif) 2 and 0<![beta](/content/p15332q626768540/xxlarge946.gif) 2.
