fits.compare | R Documentation |
Creates a class "fits.compare" object allowing the user to display model summary statistics in a form allowing easy comparison of models.
fits.compare(...)
... |
one or more class "lm", class "lm.robust" or class "TML" objects. Names given to objects in the list are used as labeling information in the printed output. |
The fits.compare
function processes its arguments one at a time to create a named list of objects.
The object returned is a member of class "fits.compare".
Because of differences in the computed summary statistics, the list of input objects is currently limited to class "lm",
class "lm.robust" and class "TML" objects.
The print.fits.compare
function displays a textual comparison of the input models,
and the plot.fits.compare
function provides comparative plots.
An object of class "fits.compare" containing the list of input models to be compared.
