Data set: asthma.text
This is a data set in ASCII format with following variables
Column1 : id.w :identification number of the subject
Column2 : trt.w: treatment assignment: 0= control, 1=drug
Column3 : start.w: Start of the at risk period
Column4 : stop.w: End of the at risk period
Column5 : st.w: censoring indicator: 0=censored, 1=event
Column6 : nn: number of at risk periods for particular subject
Column7 : fevent: indicator for first event: 0= no, 1: yes
This data set is read in by the R-program
Program: recurr.txt
This program can be submitted in R. It assumes that the file
with the data 'asthma.txt' is in the directory 'c:\'. It fits all models
both for the Weibull and the lognormal parametric assumption. It also
fits the Cox PH models provided the survival library is loaded.
