profile.brglm

Calculate profiles for objects of class 'brglm'.

Description

Creates "profile.brglm" objects to be used for the calculation of confidence intervals and for plotting.

Usage

## S3 method for class 'brglm'
profile(fitted, gridsize = 10, stdn = 5,
        stepsize = 0.5, level = 0.95,
        which = 1:length(coef(fitted)), verbose = TRUE,
        zero.bound = 1e-08, scale = FALSE, ...)

Arguments

fitted

an object of class "brglm".
gridsize

as in profileModel.
stdn

as in profileModel.
stepsize

as in profileModel.
level

qchisq(level,1) indicates the range that the profiles must cover.
which

as in profileModel.
verbose

as in profileModel.
zero.bound

as in profileModel.
scale

as in profileModel.
...

further arguments passed to or from other methods.

Details

profile.brglm calculates the profiles of the appropriate objectives to be used for the construction of confidence intervals for the bias-reduced estimates (see confint.brglm for the objectives that are profiled).

Value

An object of class "profile.glm" with attribute “level” corresponding to the argument level. The object supports the methods print, plot, pairs and confint and it is a list of the components:

profilesML

a "profileModel" object containing the profiles of the ordinary deviance for the maximum likelihood fit corresponding to fitted.
profilesBR

NULL if method = "glm.fit" in brglm. If method = "brglm.fit" and pl = TRUE, profilesBR is a "profileModel" object containing the profiles of the penalized deviance for the parameters of fitted. If method = "brglm.fit" and pl = FALSE profilesBR is a "profileModel" object containing the profiles of the modified score statistic (see profileObjectives) for the parameters of fitted.

Note

Objects of class "profile.brglm" support the methods:
