S4 class for a summary of EL objects.

## Slots

`optim`

A list of the following optimization results:

`par`

A numeric vector of the specified parameters.`lambda`

A numeric vector of the Lagrange multipliers of the dual problem corresponding to`par`

.`iterations`

A single integer for the number of iterations performed.`convergence`

A single logical for the convergence status.`cstr`

A single logical for whether constrained EL optimization is performed or not.

`logl`

A single numeric of the empirical log-likelihood.

`loglr`

A single numeric of the empirical log-likelihood ratio.

`statistic`

A single numeric of minus twice the empirical log-likelihood ratio with an asymptotic chi-square distribution.

`df`

A single integer for the degrees of freedom of the statistic.

`pval`

A single numeric for the \(p\)-value of the statistic.

`nobs`

A single integer for the number of observations.

`npar`

A single integer for the number of parameters.

`weighted`

A single logical for whether the data are weighted or not.

`coefficients`

A numeric vector of the maximum empirical likelihood estimates of the parameters.

`method`

A single character for the method dispatch in internal functions.

`control`

An object of class ControlEL constructed by

`el_control()`

.
