Comparing Weibull and Log-Normal Model II
In this exercise, we want to compare the survival curves estimated by a Weibull model and by a log-normal model for the GBSG2 data. This exercise shows how the estimates change if you use a different distribution.
The survival
, survminer
, and reshape2
packages and the GBSG2
data are loaded for you in this exercise.

Exercise instructions
- Plot the survival curves using the
ggsurvplot_df()
function. Thelinetype
should correspond to the hormonal therapy and thecolor
to the distribution (dist
).
