\title{Perform cross-validation for the ranking.}
\usage{
validate(ranking, reference_gene_ids, method_ids, progress = NULL)
}
\arguments{
\item{ranking}{The ranking to validate.}

\item{reference_gene_ids}{The reference gene IDs whose ranking should be
validated.}

\item{method_ids}{IDs of the methods that were used.}

\item{progress}{An optional progress function that should accept a single
value between 0.0 and 1.0 for progress information.}
}
\value{
A validation object with the following items:
\describe{
\item{\code{validation}}{A \code{data.table} containing percentiles of the
comparison genes from the original ranking as well as their validation.
}
\item{\code{mean_score}}{The mean score of the genes.}
\item{\code{mean_percentile_original}}{The mean percentile of the genes in
the original ranking.
}
\item{\code{mean_percentile_validation}}{The mean percentile of the genes
when optimizing without themselves.
}
\item{\code{mean_error}}{The mean absolute error.}
}
}
\description{
This function reoptimizes the ranking leaving out one of the original
reference genes at a time.
