摘要:
A necessary condition for postive dependence in the family of bivariate absolutely continuous distriburion with finite mean-square-contigency is given. It is shown, that positive dependence between two random variables implies the existence of strictly increasing reansformations of the margins which are lieart and positively correated. Similar results of SARMANOV ([9},[10],[11])are discussed
