finding derivative of a data series in R
Dear All,
I tried following for getting derivative of a polynomial in R
i<- -10:10
x<-i*i*i+3*i*i+2
fun_spline<-splinefun(i,x)
plot(x,type="l")
lines(x,fx_spline(x, deriv=1), col='green')
lines(x,fx_spline(x, deriv=2), col='green')
Now when I plot
3*i*i + 6*i and 6*i + 6
the plot was not same for first deivative.
where as the 2nd derivative was same

QQ International -- Almost works, but always says I'm "Away"
I got QQ International (version 1.0) to work via WINE under Mepis 8.5. Using winetricks, I installed all of the missing DLL's, and QQ now starts up and runs fine.
... except for the fact that it always shows me as being "Away". Even if I manually set my status to "Online", it changes me back to "Away" after a second or two.
This only happens under WINE. I log in

QQ International - How to troubleshoot an app that wont run?
As I mentioned in the subject, I have installed the latest version of QQ International (beta 3), under wine in ubuntu lucid.
It installs without much trouble, however when I run the application, nothing happens.
How do I begin troubleshooting this application to see if I can make it work?
Or if anyone happens to know of an x64 linux qq client that actually works that would be great too :D

Quantiles and QQ plots
I have 20 variables:
5,9,6,1,5,9,7,4,5,6,3,2,4,8,9,6,1,8,4,8
How do I calculate the corresponding quantiles from a normal distribution
with the same mean and variance as the sample?
Also, how do I draw a QQ plot of the data?
Thanks for any help!

Video call with QQ or any messenger
Hi everyone,
I'm a newbie to wine, and am working on QQ or any other messengers in wine.
My environment is : ubuntu 10.04, installed wine 1.1.42, QQ2009. And during my debugging, I also check some source code from latest wine 1.2-rc4.
Although QQ's level is "garbage", but fortunately it works almost fine under wine, including login, text chat, ..... But the video call can only

strange QQ-Plot
Hi,
i am working on a data set with EDA. That includes QQ-Plots of
residuals vs expected normal distribution.
What puzzles me is that the range of ordinate and abscissae is
so different: while the theoretical quantiles range from [-2, 2]
the sample quantiles on the ordinate do extent from [-20, 50].
Quite obviously some kind of transformation is done.
Although i intensively RTFM i could not

(-1 as index) OR (envelope for QQ)
I'm new to R (and to S) and am wondering about code from pages 72 and
83 of MASS (Venables+Ripley, 3rd edition), to draw an envelope on a QQ

num.points <- length(resid(a.fit))
qqnorm(residuals(a.fit)) # illustrate data-model residuals

correlation coefficient from qq plot
Hi,
I am trying to figure out how to get the correlation coefficient for a
QQ plot (residual plot). So to be more precise, I am creating the plot
like this:
qq.plot(rstudent(regrname), main = rformula, col=1)
But want to also access (or compute) the correlation coefficient for
that plot.
Thanks,

QQ plot for normality testing
Hi all,
I am trying to test wheater the distribution of my samples is normal with QQ plot.
I have a values of water content in clays in around few hundred samples. Is the code :
qqnorm(w) #w being water content
qqline(w)
sufficient?
How do I know when I get the plots which distribution is normal and which is not?
Thanks, m

QQ-plot – Axes
I would like to change the position of the major tick marks in my qq-plot?
Right now the ticks are set at 5.5, 6.0, 6.5 and 7.0.
I would like them to be at 5.4, 5.6, 5.8, 6.0, 6.2, 6.4, 6.8 and 7.0. So I
would have to remove some of the present ticks. So far I can only add ticks
to the plot with:
axis(1,at=c(5.4, 5.6, 5.8, 6.0, 6.2, 6.4, 6.8, 7.0))

Deriving Samples from specific, not implemented PDF for a QQ-Plot

this is my first post to the R-help, so please don't be too strict.
My problem concerns a QQ-Plot:
I want to show how well empirical samples match with a theoretical

made it to fit via ML.
Anyway, the theoretical function gives me the density for a given data point
