WeibullR (version 1.2.4)

plot_contour: Plotting of Likelihood Ratio Contours from wblr Objects

Description

Plots likelihood ratio contours from a wblr object or a list of wblr objects.

Usage

plot_contour(x, CL=NULL, AL=TRUE, ...)

Value

This function returns the list of contours that were prepared for plotting.

Arguments

x

Object of class "wblr" or a list of "wblr" objects.

CL

An optional argument for establishing the confidence limit(s) for calculated contours. A vector of values may be provided to generate concentric contours on a single object.

AL

A Logical defining whether parameters of lognormal contours should be presented as AntiLog values.

...

Entry for a limited set of graphic parameters (col, lty, lwd, xlim, ylim, main and sub)

Details

If no CL argument is provided, the contours generated in the provided wblr objects for likelihood confidence bounds will be plotted. If a vector is provided for CL, multiple contours for each provided object will be calculated to display concentric contours according to values in the CL vector. In all cases options for distribution, degrees of freedom and graphic options will be extracted from the underlying objects.

Examples

set.seed(1234)
fail<-rweibull(5,2,10)
ctest<-wblr(fail)
ctest<-wblr.fit(ctest, method.fit="mle")
ctest<-wblr.conf(ctest, method.conf="lrb",col="red")
fail2<-c(10,40,40,50)
susp<-c(20,60)
ctest2<-wblr(fail2, susp)
ctest2<-wblr.fit(ctest2, method.fit="mle")
ctest2<-wblr.conf(ctest2, method.conf="lrb",col="blue")

if (FALSE) {
 plot_contour(list(ctest, ctest2))
}
