check_optim

Checks that the arguments supplied by the user are appropriate to be passed
to <code><a href="/link/optim()?package=joker&version=0.14.2" data-mini-rdoc="joker::optim()">optim()</a></code>. Used internally in parameter estimation.

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.
