\title{Confidence intervals for parameters of mkinfit objects}
\usage{
\method{confint}{mkinfit}(object, parm, level = 0.95, alpha = 1 -
level, method = c("profile", "quadratic"), transformed = TRUE,
backtransform = TRUE, distribution = c("student_t", "normal"),
quiet = FALSE, ...)
}
\arguments{
\item{object}{An \code{\link{mkinfit}} object}
\item{parm}{A vector of names of the parameters which are to be given
confidence intervals. If missing, all parameters are considered.}
\item{level}{The confidence level required}
\item{alpha}{The allowed error probability, overrides 'level' if specified.}
\item{method}{The 'profile' method searches the parameter space for the
cutoff of the confidence intervals by means of a likelihood ratio test.
The 'quadratic' method approximates the likelihood function at the
optimised parameters using the second term of the Taylor expansion, using
a second derivative (hessian) contained in the object.}
\item{transformed}{If the quadratic approximation is used, should it be
applied to the likelihood based on the transformed parameters?}
\item{backtransform}{If we approximate the likelihood in terms of the
transformed parameters, should we backtransform the parameters with
their confidence intervals?}
\item{distribution}{For the quadratic approximation, should we use
the student t distribution or assume normal distribution for
the parameter estimate}
\item{quiet}{Should we suppress messages?}
\item{\dots}{Not used}
}
\value{
A matrix with columns giving lower and upper confidence limits for
each parameter.
