+\arguments{
+\item{object}{An mkinfit object to be updated}
+
+\item{\dots}{Arguments to \code{\link{mkinfit}} that should replace

+\description{
+This function will return an updated mkinfit object. The fitted degradation
+model parameters from the old fit are used as starting values for the
+updated fit. Values specified as 'parms.ini' and/or 'state.ini' will
+override these starting values.
