German Breast Cancer Dataset

This dataset is courtesy of Patrick Royston and Willi Saurbrei. It is the official version of a dataset from the website for their book Royston P, Sauerbrei W, Multivariable Model-Building, Wiley, Chichester, 2008. Details of the dataset are on pp. 262-263 of their book. Some redundant variables from the tab-delimited ASCII version of the dataset have been deleted. The R file was created with the code below. library(Hmisc) gbsg <- csv.get('gbsg_ba_ca.dat', sep='\t') for(i in 1:length(gbsg)) label(gbsgI) <- '' with(gbsg, table(X.d,censrec)) with(gbsg, table(round(rectime/X.t,2))) with(gbsg, table(grade, paste(gradd1,gradd2))) redun(~., data=gbsg) gbsg <- upData(gbsg, rename=c(X.st='st', X.d='d', X.t='t', X.t0='t0'), drop=c('rectime','censrec','gradd1','gradd2','st','t0'), labels=c(d='censrec', t='rectime/365.25', grade='1:gradd1=0 gradd2=0,2:1 0,3:1,1'), levels=list(meno=c('postmenopausal','premenopausal'))) # Note: t0 was constant at 0, st at 1 redun(~., data=gbsg) Save(gbsg)
