\title{
Calculate the minimum error to assume in order to pass the variance test
}
\description{
This function uses \code{\link{optimize}} in order to iteratively find the
smallest relative error still resulting in passing the chi-squared test
as defined in the FOCUS kinetics report from 2006.
}
\usage{
kinerrmin(kinfits, kinmodel = "SFO", alpha = 0.05)
}
\arguments{
  \item{kinfits}{
The list of kinetic model(s) from which to select. Usually this will have been
generated by \code{\link{kinfit}}.
}
  \item{kinmodel}{
The kinetic model to be checked. Should be one of the names of the kinetic models used for generating \code{kinfits}.
}
  \item{alpha}{
The confidence level chosen for the chi-squared test.
}
}
\value{
The relative error, expressed as a fraction.
}
