profile.brglm {brglm} | R Documentation |
Creates "profile.brglm"
objects to be used for the calculation of
confidence intervals and for plotting.
## 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, ...)

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).
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 . |
Objects of class "profile.brglm"
