Confidence Band for empirical distribution function
Hi,
I was trying to draw an empirical distribution function with uniform
confidence bands. So I tried to find a way to calculate values of the
Kolmogorov-Smirnov Distribution but failed.
I guess it must be hidden somewhere (since the ks-test is implemented),
but I was unable to find it.
Is there any way to do this?
Thanks

A modified log transformation with real finite values for negatives and zeros?
Does anyone have any ideas (or even experience) regarding a
modified log transformation that would assign real finite values to
zeros and negative numbers? I encounter this routinely in a couple of
different situations:
* Physical measurements that are often lognormally distributed
except for values that are less than additive normal measurement error.
I'd like to take

Two questions
Greetings,
I have two questions that I could not answer from the
documentation.
A - ecdf and confidence intervals : Is there a (simple) way to generate
confidence intervals (95%) for a ecdf?
B - cross-validation of rpart trees : a colleague is using S to
generate decision tree and mentioned to me the use of cross-validation. Is
this function enabled in R ? if so, how should one proceed to
