چکیده

‎We proposed and studied a new bivariate random sign transformation of nonnegative bivariate integer-valued distributions‎. ‎This transformation develops new bivariate integer-valued distributions on $Z^{2}$. We applied the new transformation to the bivariate Poisson  and the bivariate geometric distributions‎. ‎As an illustration‎, ‎we fitted a real-life data set developed based on the results of the 2019 UEFA Europa League using the new distributions‎.
