Calculates the forward difference of a vector or matrix.

internal

Implements an S4 distribution system and estimation methods for
parameters of common distribution families. The common d, p, q, r function
family for each distribution is enriched with the ll, e, and v counterparts,
computing the log-likelihood, performing estimation, and calculating the
asymptotic variance - covariance matrix, respectively. Parameter estimation
is performed analytically whenever possible.
