+  Function to plot the confidence intervals obtained using

+\description{
+  This function plots the confidence intervals for the parameters
+  fitted using \code{\link{mkinfit}}.
+}
+\usage{
+  mkinparplot(object)
+}
+\arguments{
+  \item{object}{
+    A fit represented in an \code{\link{mkinfit}} object.
+  }
+}
+\value{
+  Nothing is returned by this function, as it is called for its side effect, namely to produce a plot.
