A Maple algorithm for k-statistics, polykays and their multivariate generalization

This algorithm has been inserted in the MapleSoft Application Center Through the classical umbral calculus, we provide a unifying syntax for single and multivariate k-statistics, polykays and multivariate polykays. Classical umbral calculus is a symbolic method for handling ordinary and exponential formal power series. A feature of the classical umbral calculus is that an umbra has the structure of a random variable but with non reference to a probability space. This brings the umbral syntax closer to statistical methods.
