Hi list,
this is my second try for first post on this list (I tried to post via email
and nothing appeared in my email-inbox, so now I try to use the
nabble-web-interface) - I hope that you will only have to read one post in
your inbox! Okay, my question ...
I was able to plot a histogram and add
Thanks, I found the function ecdf() which does the job.
plot( ecdf( nvtpoints), col="BLUE", lwd=1, add=TRUE )

Hi,
I am using ecdf-function and want to use the ecdf()-data-points for nls() as
data-parameter.
nls() expects 'list' or 'environment' as a data-type, knots(ecdf(mydata))
gives me 'numeric'.
What should I do now?
Thanks in advance - Jochen
Here is the code:

Thanks David and Peter!
I tried to improve my R-script to get closer to my goal.
I guess I have to use nls(), because later I want to work with
Levenberg-Marquardt-Algorithm and when I got it right, LM-Algorithm uses
least squares as well, fitdistr() instead uses Maximum Likelihoods. Anyway,
I am
Hi David,
my first attempt to work through your code was successful, my predicted line
is pretty close to the ecdf-function. I have no idea why you inverted the
gumbel-function and what the advantage of this strategy is?
I interpret your (1:100/100)-trick like this: you build a sequence of 100

Ok, I think I had a good idea to solve my problem and need someone who second
me on that or tell me what a fool I am :-) .
My problem: I went for curve-fitting with nls() and took knot()-ecdf() for
collecting data for nls-basis-dataframe. I came into trouble, because my
x-y-data of the data.frame(
Hi,
I am looking for an opportunity to make a KS-Test in my C/C++-app.
Unfortunately I am not able to find a lib or function in C or C++ which does
the job. For my other numerical stuff Gnu Scientific Library was recommended
to me. What to do now?
I read that there are options to call R in C++-C
Hi,
I got two data point vectors. Now I want to make a ks.test(). I you print
both vectors you will see, that they fit pretty fine. Here is a picture:

As you can see there is one histogram and moreover there is the gumbel
density
Hi, I used a ks-function of another library (kstwo() of numerical recipes, a
mathematics book) to test it for myself and the same happens there - I
cannot understand why this observation happens? I hope someone can
'enlighten' me.

Hi R-Users,
I read some texts related to KS-tests. Most of those authors stated, that
KS-Tests are not suitable for binned data, but some of them refer to 'other'
authors who are claiming that KS-Tests are okay for binned data.
I searched for sources and can't find examples which approve that it
