Hello,
I put my data in conditional counting process format basically by adding
a stratum variable to distinguish between observations.
I fit a model and then used survfit function. These are the first five lines
of
output.
time n.risk n.event survival std.err lower 95% CI upper 95% CI
8
Hi,
I created an rpart object and pruned the tree using
1-SE rule. I used 10-fold cross validation while
creating the tree. Then, I extracted the
cross-validated predictions for my data points using
xpred.rpart and obtained some statistics like
precision, recall, overall error rate, etc.
However,
rs. I appreciate your helps in advance.
Regards
A. Gunes Koru
