Hello,
I'm not sure I understand the question, but is it something like this?
set.seed(3648)
x <- rnorm(100)
plot(ecdf(x), cex = 0.5)
# Now create a function; don't use
# uppercase F, it's a symbol for FALSE.
f <- ecdf(x)
f(0) # Should be near 0.5
Hope this helps,
Rui Barradas

Dear all,
I would like to estimate (mathematically express) the ecdf of a random
variable using a curve fitting technique. Can anyone help me how to do this?
Thanks.
