psi and showing its profile log likelihood and modified profile log likelihood. Two further plots are produced if all=TRUE, and tests are performed if psi is given a value.## S3 method for class 'fr':
plot(x, psi = NULL, all = FALSE, xl = "Interest parameter", \dots)tem.psi for which tests may be required.all=T two additional plots are added.psi=NULL, draws graphs showing: (top left) the likelihood root r, the modified likelihood root rstar, the Wald pivot z, and the likelihood modification q as functions of the parameter psi; (top right) the profile log likelihood and
modified profile log likelihood as functions of psi; (lower left) the significance functions corresponding to the upper left panel; and (lower right) how the modification log(q/r)/r depends on r. If all=FALSE (the default) only the upper two graphs are plotted. The lower left panel is a transformation of that above it, and the lower right panel is intended as a possible diagnostic of failure of the asymptotic approximations; it should be a smooth function of r.
If psi is given a (single, scalar) value, then the significance functions for the Wald statistic, the likelihood root, and the modified likelihood root, are evaluated at this value, providing p-values for testing against larger values of psi.tem, summary.fr, lik.ci## See the examples to \link{tem}.Run the code above in your browser using DataLab
