Nice to meet you Brian. The question is about the numbers that appears after lambda (0,0, 0.1, 0.0001). I know that seq is a set of values used for testing which value fits best. But I'm not sure if I need to put whatever I think or what. I tried also with a set of 5 values and I get an error. Is there a maximum allowed?
plot(lm.ridge(hipcenter ~ .,seatpos, lambda = seq(0,0.1,0.001))) select(lm.ridge(hipcenter ~ ., seatpos,lambda = seq(0,0.1,0.001))) __________________________________________________________________ *Rodrigo Briceño* Project Manager Sanigest Internacional +506 22-91-12-00 ext. 113 * Oficina* *Costa Rica* +506 22-32-08-30 *Fax *+506 88-86-11-77* Celular** [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> www.sanigest.com <http://www.sanigest.com/> MSN: [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> SKYPE: rbriceno1087 _____________________ This communication contains legal information which is privileged and confidential.
