plot.confreg {chandwich}  R Documentation 
plot
method for class "confreg".
Plots confidence regions for pairs of parameters using the profile
loglikelihood values calculated by conf_region
.
Up to 4 different types of loglikelihood (see the argument type
to the function returned by adjust_loglik
)
may be superimposed on the same plot.

conf 
A numeric vector of confidence levels, i.e. numbers in
(0, 100). A confidence region contour is plotted for each value in

legend 
A logical scalar or a character vector. If this is
supplied then a legend is added to the plot. If 
legend_pos 
The position of the legend (if required) specified using
the argument

Nothing is returned.
See the examples in conf_region

adjust_loglik
to adjust a usersupplied
loglikelihood function.
conf_region
for a confidence region for
a pair of parameters.
conf_intervals
and plot.confint
to
plot confidence intervals for individual parameters.
