Through the classical umbral calculus, we provide new, compact and easy to handle expressions for k-statistics, and more generally for U-statistics. In addition, this symbolic method can be naturally extended to multivariate cases and to generalized k-statistics.

Through the classical umbral calculus, we provide new, compact and easy to handle expressions for k-statistics, and more generally for U-statistics. In addition, this symbolic method can be naturally extended to multivariate cases and to generalized k-statistics.
