Area between CDFs
Dear List:
I am trying to find the area between two ECDFs. I am examining the gap in performance between two groups, males and females on a student achievement test in math, which is a continuous metric.
I start by creating a subset of the dataframe
male<-subset(datafile, female="Male")

CDFs
Hello all,
I have two columns of numbers. I would like to do the following:
(1) Plot both cdfs, F1 and F2 on the same graph.
(2) Find smoothed approximations of F1 and F2 lets call them F1hat and F2hat
(3) Find values for F1hat when we substitue a value of x in it.
(4) Find the corresponding densities of the cdfs.
Any ideas?

multiple plots in a graph
Hi,
I have to generate 10 cdfs in a graph. I need to compare the cdf's
nature by plotting ten cdfs in a graph. Thus, I need multiple plots in a
graph.
I would appreciate if you could give some solution to the problem asap.
Thanking you,
Sincerely,
Ajay.

TRANS.TBL files on Win95 fileserver
I have a small LAN in my basement, with my PC running RH5 Linux and a Win95 PC
connected by Samba. Everything works fine, but when I smbmount a CD (burned
with xcdroast) from the Linux box (CD is in the Win95 machine) I do not get the
proper filenames. All files are uppercase, and the TRANS.TBL files appear to be
ignored. I have tried playing with name mangling, but it didn't help. Is this a

Audio CD problem
Hello
I just downloaded a great program called Transcribe (to slow down music
so you can learn it) available at http://www.seventhstring.demon.co.uk/
and it worked smoothly and without problem through Wine on my Gentoo 1.4
laptop. The problem is that the program wants to open .cda files to
access the CD tracks and I don't know about a way to mount audio CDs in
Linux. I could of course rip the

plotting least-squares regression against x-axis
Hi,
I want to plot the residuals of a least-squares regression.
plot(lm(y~x), which=1)
does this, but it plots the y-axis of my data on the x-axis of the
residuals plot. That is, it plots the residual for each y-value in the
data. Can I instead use the x-axis of my data as the x-axis of the
residuals plot, showing the residual for a given x?
Thanks!

Kolmogorov-Smirnov: calculate p value given as input the test statistic
Dear all,
I calculate the test statistic for the KS test outside R, and wish to use R
only to calculate the corresponding p-value.
Is there a way for doing this? (as far as I see, ks.test() requires raw
data as input). Alternatively, is there a way to provide the ks.test() the
two CDFs (two samples test) rather than the (x, y) data vectors?
Thanks in advance,
Rani

Problems with multiboot DVD and isolinux > 3.07
Hi,
some time ago I tried to boot an isolinux boot loader from another one
to be able to boot e.g. a Knoppix CD with its original boot loader and
menus from a "main" isolinux on a multiboot DVD.
This works for isolinux <= 3.07 now!
However, newer isolinux boot loaders have some problems and the isolinux

ks.test - The two-sample two-sided Kolmogorov-Smirnov test with ties (PR#13848)
...in ks.c calculates this probability by enumerating all such assignments as
lattice walks, except that it doesn't know how to handle tied data points.
The correct procedure can be deduced by considering that steps in such lattice
walks represent steps along the x-axis in computing the empirical CDFs of the
two data sets. The trick is to consider all occurrences of a repeated data
point together, when determining whether a path exceeds the input statistic or
not. A FORTRAN implementation of this algorithm was published by Nikiforov
(http://www.ams.sunysb.edu/~nkfr/5PUBL.HTM), but it's not...

Poor family objects error messages

The documentation is correct but misleading too.
> The gaussian family accepts the links (as names) identity, log and inverse; the binomial family the

Without changing the language, this could be fixed by changing the error messages to something more suggestive.

Special Functions calculations
...d quantiles are calculated.
I have already calculated the normal probability values using a Taylor
expansion (http://www.sisweb.com/math/tables.htm).
I realize these calculations must be very difficult, but I think it is
insulting to our intelligence by mathematicians to hide the solutions to
the CDFs from us like this.

Help with Ecdf function
Dear R users,
I'm using Ecdf (Hmisc library) to plot four cdf in a same graphic. In this
graphic I also plot the 0.99 quantile for these cdf. I successfully plot
cdfs using different types of line to distinguish them, but I can't
determine the type of lines showing 0.99 quantile.
Is there a way to assign different line types for quantile lines in Ecdf
plot?
Best regards,

Yet another attempt at /tmp spoof protection
-----BEGIN PGP SIGNED MESSAGE-----
Hi all,
Prompted by Mark''s discussion of the transname patch I''ve put together
an experimental patch to the Linux nfsd that supports something I''ve named
CDFs for lack of a more appropriate name. They''re not real CDFs, and in
particular, they won''t let you manage stuff like shared /etc directories
for diskless clients (it breaks /etc/mtab handling, for instance). I''m
not particularly proud of it since I consider CDFs a kludge...

nlm() problem or MLE problem?
...imate[1], out$estimate[2])
lines(xfit,yfit,lty=2)
yfit2<-pweibull(xfit,a, b)
lines(xfit,yfit2)
list(out=out)
}
I got the starting values a=9, b=.27 from fitting the Weibull CDF by eye
to a quantile plot of the data. The final values fitted by nlm() are a=
4.8299357, b= 0.2753897
I plotted both CDFs against the quantile plot of the data. I would have
expected the MLE fit to be the one that lies closer to the data. NO.
The MLE solution (dashed) seems to fit quite badly in comparison with my
starting values (solid).
I wonder if this is just the way MLE is, or is there a problem with nlm()
here?...

truncated normal
Hi, I want to generate random samples from truncated normal say
Normal(0,1)Indicator((0,1),(2,4)). It has more than one intervals. In the
library msm, it seems to me that the 'lower' and 'upper' arguments can only
be a number. I tried rtnorm(1,mean=0,sd=1, lower=c(0,2),upper=c(1,4)) and it
didn't work. Can you tell me how I can do truncated normal at more than one
intervals?
