+\alias{AIC.mmkin}
+\title{
+ Calculated the AIC for a column of an mmkin object
+}
+\description{
+ Provides a convenient way to compare different kineti models fitted to the
+ same dataset.
+}
+\usage{
+ \method{AIC}{mmkin}(object, ..., k = 2)
+}
+\arguments{
+ \item{object}{
+ An object of class \code{\link{mmkin}}, containing only one column.
+ }
+ \item{\dots}{
+ For compatibility with the generic method
+ }
+ \item{k}{
+ As in the generic method
+ }
+}
+\value{
+ As in the generic method (a numeric value for single fits, or a dataframe if
+ there are several fits in the column).
+}
+\examples{
+ f <- mmkin(c("SFO", "FOMC", "DFOP"),
+ list("FOCUS A" = FOCUS_2006_A,
+ "FOCUS C" = FOCUS_2006_C))
+ AIC(f[1, "FOCUS A"]) # We get a single number for a single fit
+
+ # For FOCUS A, the models fit almost equally well, so the higher the number
+ # of parameters, the higher (worse) the AIC
+ AIC(f[, "FOCUS A"])
+ AIC(f[, "FOCUS A"], k = 0) # If we do not penalize additional parameters, we get nearly the same
+
+ # For FOCUS C, the more complex models fit better
+ AIC(f[, "FOCUS C"])
