| Abstract: | A two-variable Walsh characteristic function is identical to the double-Walsh transform of the probability density function. In a similar manner, an n-variable Walsh characteristic function and moment can be defined. It is now possible to derive moments from Walsh characteristic function via a dyadic derivative operator. |
