\title{
  Calculated the log-likelihood of a fitted mkinfit object
}
\description{
  This function simply calculates the product of the likelihood densities

}
\usage{
\method{logLik}{mkinfit}(object, ...)
}
\arguments{
  \item{object}{
    An object of class \code{\link{mkinfit}}.
  }
  \item{\dots}{
    For compatibility with the generic method
  }
}
\value{
  An object of class \code{\link{logLik}} with the number of
  estimated parameters (degradation model parameters plus variance
  model parameters) as attribute.
