Hello, I am constructing a nomogram using cph and nomogram commands in Dr. Harrell's Design/RMS package. The HR that I obtain for dichotomous and categorical variables are identical to those that I obtain using STATA stcox. However, the inter-quartile HR I obtain for continuous variables is obviously different, since STATA gives me HR for each unit (year, centimeter, etc) like coxph would give. My question is if this will effect the output of the nomogram. I'm assuming that nomogram is constructed using hazard between each unit rather than quartiles - is this true?
Also, I've found that I do not need to create indicator variables for my categorical variables when I use cph. Is this also correct? I appreciate your feedback. Thank you. ~Renee -- View this message in context: http://r.789695.n4.nabble.com/cph-nomogram-Design-RMS-package-hazard-ratio-interquartile-vs-per-unit-tp3923896p3923896.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.
