The functions variance, skewness, and kurtosis are new
generic functions for computing moments of probability distributions such as
those provided in this package. Additionally, the probability distributions
from distributions3 all have methods for the mean
generic. Moreover, quantiles can be computed with methods for
quantile. For examples illustrating the usage with
probability distribution objects, see the manual pages of the respective
distributions, e.g., Normal or Binomial etc.
