R devel - Jun 2006 - Bug in R-intro.html ? (PR#9028)

Submission from: (NULL) (84.143.196.187)


Hi,

Presumably, I've found an error in
http://finzi.psych.upenn.edu/R/doc/manual/R-intro.html

In Chapter 11.3 Generic functions for extracting model information it says
"Select a suitable model by adding or dropping terms and preserving
hierarchies.
The model with the LARGEST value of AIC (Akaike's An Information Criterion)
discovered in the stepwise search is returned." Shouldn't it read
"with the
SMALLEST value ..."?

Sorry, if I only misunderstood the meaning of "returned"!

By the way: Thank you very much indeed for developing this great free software!


Sincerely
Ommo H?ppop

yes indeed.  Astonishing how long something like this remains
unnoticed or at lt least unnoticed by the good guys who
contribute back to the project by concise bug reports.

Thank you.
