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.
# S3 method for confreg
plot(x, y = NULL, y2 = NULL, y3 = NULL,
conf = 95, legend = any(c(!is.null(y), !is.null(y2), !is.null(y3))),
legend_pos = "topleft", ...)
objects of class "confreg", results of calls to
conf_region
for a common model and a common value of
which_pars
. Contours are plotted for each object.
A numeric vector of confidence levels, i.e. numbers in
(0, 100). A confidence region contour is plotted for each value in
conf
.
A logical scalar or a character vector. If this is
supplied then a legend is added to the plot. If legend
is a
character vector then it is used as the argument legend
to legend
. Otherwise, i.e. if
legend = TRUE
then the component type
of the input
object(s) x, y, y2, y3
are used.
The position of the legend (if required) specified using
the argument x
in legend
.
Nothing is returned.
See the examples in conf_region
.
adjust_loglik
to adjust a user-supplied
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.
