Consider the following generic code for a survival model survobj<-Surv(data$Time,data$Satisfactory) survmodel<-survreg(survobj~x1+x2+x3+x4+x5+x6, data=data, dist="weibull") survsum<-summary(survmodel) survsum
My question: Does anyone know what exactly survreg() does differently if x1<-factor(data$x1, ordered=TRUE) x2<-factor(data$x2, ordered=TRUE) vs. x1<-factor(data$x1) x2<-factor(data$x2) Thanks, William -- View this message in context: http://r.789695.n4.nabble.com/How-does-survreg-ordered-factors-vs-not-ordered-factors-tp4580395p4580395.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
