single 
name
character
. The name of each model
model.class
character
. One class to which each model belongs
nested
data.frame
. Model fit comparisons between adjacently
nested models that are ordered by their degrees of freedom (df)
fit
data.frame
. Fit measures of all models specified in the
name
slot, ordered by their df
