In profileCI: Profiling a Log-Likelihood to Calculate Confidence Intervals

Methods for objects of class "profileCI"

Description

Methods for objects of class "profileCI" returned from profileCI.

Usage

## S3 method for class 'profileCI'
print(x, ...)

## S3 method for class 'profileCI'
plot(x, parm = 1:nrow(x), add = TRUE, digits = 2, ...)

Arguments

x	An object inheriting from class ⁠profileCI"⁠, a result of a call to profileCI.
...	Further arguments. For ⁠print."profileCI"⁠ to pass arguments to print. For plot.profileCI to pass graphical parameters to graphics::plot to create the initial plot of the profile log-likelihood.
parm	A numeric or character scalar specifying the parameter for which a profile log-likelihood is plotted. Must be a single component consistent with the argument parm to profileCI.
add	A logical scalar. If add = TRUE then the plot is annotated with a horizontal line indicating the critical value for the profile log-likelihood used to calculate the confidence limits, vertical lines indicating the values of these limits and a legend stating the confidence interval.
digits	An integer. Passed to signif to round the confidence limits in the legend, if add = TRUE.

Details

print.profileCI. A numeric matrix with 2 columns giving the lower and upper confidence limits for the parameters specified by the argument parm in profileCI. These columns are labelled as (1-level)/2 and 1-(1-level)/2, expressed as a percentage, by default ⁠2.5%⁠ and ⁠97.5%⁠.

plot.profileCI. A plot is produced of the profile log-likelihood for the parameter chosen by parm. Only the parameter values used to profile the log-likelihood in the call to profileCI are included, so if faster = TRUE was used then the plot will not be of a smooth curve but will be triangular in the middle.

Value

print.profileCI: the argument x is returned, invisibly.

plot.profileCI: a numeric vector containing the confidence interval for the parameter chosen for the plot.
